I like the Obamacare idea, but am against raising taxes. Actually, I think taxes should be much, much lower. I believe that those who need help should get it. But I can’t stand lazy *** people on welfare who don’t need that money. Dont mooch off the damn government. Haha – anyway, thanks for all good answers!

How would Americans feel if they knew the Obama administration just agreed to hand people affiliated with a designated terrorist group a $30 billion dollar check and recognize them as the legitimate rulers of Libya?
Things weren’t looking so good for the Libyan Islamic Fighting Group back in 2004 when they were designated a foreign terrorist group by the State Department. In chilling testimony, then-CIA Director George Tenet warned the Senate Intelligence Committee in 2004 that even if Osama bin Laden’s al-Qaeda was completely destroyed, “a global network of Islamic extremists bent on killing Americans had emerged.” Tenet listed the Libyan Islamic Fighting Group (LIFG) as one of those groups.
In 2007, the LIFG formally joined al-Qaeda, an event so well documented that even Reuters covered it. Its goals, which it is now close to achieving thanks to airpower help from President Obama and NATO, include killing Libyan leader Muammar Gaddafi, setting up an Islamic caliphate in Libya and waging international jihad.
The known leaders of the Libyan rebel forces on the ground are all former LIFG fighters, some with documented personal connections to al-Qaeda. The Transitional National Council, which the Obama administration recognized last week as the official government of Libya, is packed with pro-LIFG activists, lawyers who have advocated for imprisoned LIFG fighters, and Islamic scholars from LIFG strongholds.
Something smells strongly of jihad here. http://www.humanevents.com/article.php?i…

Is my life epic enough to sell to a book writer? And is it even possible to sell my life story to a book writer or film maker?
My Mom had a afair with her sisters husband. I was a created from the afair. I never knew I was a product of a afair. My mom hates me, and blames me for being born. Because my moms husband is african american, so its very obviouse my mom had a afair. Despite this my mom, and step dad lied to me, and told me I was mixed. I grew up getting into fights with black people telling me Im not black, and me telling them I am. I saw my face as mixed even though I am obviosly white. I have a point European nose, and jewish features. Light brown even blondish hair, and blue eyes.My mom left me and took my brothers and sisters with her when I was 16 teen. She came back a year later and continued hating me. She would have my older brother beat me up, even jump me with other kids. She would buy, or make dinner for all my siblings except me. And she even told me every day I am a retard, and will never be anything. She ment it literally, that I had a mental disability. The guidence counselor at my school tried to tell her I scored the highest on the state math test. And that I should go to college, and asked her to sign a schollarship paper. My mom told the guidence counselor im a little retart , and I am not going to college. She then(my mom) told me to get a job at a factory.She planned to make me un marriable and have me forever tucked away in her basement hiding the secret. But I was handsome girls would call the house, guidence counselors were knocking because I was smart. So to solve her problem she kicked me out the house, and had me disowned from the whole famly cuzins, and all. She told them I was a bad terrible son. I stayed in agroup home, and still finished my senior year of high school. the group home had a step program to get those kids working a apartment. I found a job quickly, and was going to get the apartment. Until my mom called the week before knowing said she wants me to come home. My mom and dad had been seperated for the 2 months I was gone. The day I came back my step Dad sucker punched me in the mouth my mom told the police it was my fault and they locked me up. I spent three days in jail till my cuzin bailed me out. My Dad droped the fake charges because it was bringing my Mom un wanted attention. Then I finally figured out why my mom was doing this, and that I was a product of a afair. I acidently bumped into my uncle, that I was never aloud to see, or be at the same famly get togethers as. He had my face, even my weird hands. My ant told me that the afair happend when they had a 1year old sone and a 2 yearold son, and when. that placed the afair at nine months before I was born.I eventually made into NYU( a good school). I teach kids who go through abuse like me. And I even act or try to be a star.I was on one collegehumor sketh , and had one speaking under 5 in a movie.I actually even landed a lead in a NBC pilot that was cancled. Sorry Im babbling. But really what do you think? Is this worthy of a novel? theres other small stories in my life that go with my story. Like the time I caused a huge union strike at a supermarket I worked at for discriminating agianst me. I won and the racist super market was forced to finaly hire minoritys from the section 8 housing project across the street.I came from little rochester new york to big NYC by myself.I put on a whole theater show before with a simple marketting plan and fufilled my first dream of doing sketch comedy. My first modeling gig the guy wiped out his meat and put porn on , and said I need you to be more sexy. I ran away! My x threw a brick at my friend because she was jealouse. And made me loose my voice before my first audition because swhe was so jealose/insecure (it was a sex scene). My baby sister would always talk to me, and play with me. I decided I could never see her again when my mom slammed her head into the wall for talking to me. She was hysterical when that happened, and hysterical when I told her at 5 I wasnt going to be able to see her for a long time. I had asmthma so my mom washed all the room walls in clorox. I started to turn blue(my lips) so she put me in a beach chair sitting up. And told me I dont want to pay for a ambulance we cant aford it. And the car doesent run well. My aunt busted in and drove me to the hospital the 1o minute ride. The doctor looks at my mom and tells her I only had 10 or 15 minutes to live.I think this could be a book, but maybe theres plenty of stories like that already?so what do you think?novelist will take it?

I am thinking about setting up a travel website which offers website visitors information on various locations around the world but I am skeptical about the idea as any affiliate earnings will only come through during the summer right? By the time I have actually created the site, summer 2011 will be over so I will have to wait until next year to see any real results. Am I right in thinking this?
