Affiliate Marketing Secrets

Is it possible for any religious organization to censor what it’s members read? I’m not talking about countries where the government is one of religious nature and therefore what the religion says the government follows through with it. I’m referring to religious bodies or organizations whether loose knit or close community; could the leaders of the organization actually censor or ban what its’ members read? For instance, where I live there are various organizations affiliated with different religious groups. So can one organization that is affiliated with Hinduism censor what it’s members read? Or can one organization that is affiliated with Christianity, such as Roman Catholicism or Anglicanism censor what it’s members read? I know that religious leaders and organizations can advise against reading such and such. But is it possible that they can implement stricter policies?

Someday we will make contact with a sentient species from another planet or galaxy, I am completely positive about that. What I was wondering is, if our species are gonna be in contact with each other constantly then it will be quite obvious that at some point we will try breeding with each other. How would all major religions deal with this (i.e Islam, Catholicism, Buddhism, Hinduism)? Would they be ok with it? Or would they call it bestiality?
I posted this here because I wanted to know what you guys think. If you are not affiliated with any religion that’s okay, just try to answer with an open mind.
