Affiliate Marketing Secrets

I was having a discussion with a Christian affiliate, deploring him of his one-sided argument and ways, so I told him “Harry Potter died for your sins! Show some respect, muggle!” He thought this was way out of line, and I hardly see why. Time and time again people have told me that “Jesus died for your sins” why can’t I use the same response only in reference to Harry Potter. Both are true; Harry Potter did indeed sacrifice his life to protect wizards and muggles alike from Lord Voldemort, so why be offended?? I am not belittling your faith, we just happen to invest our faith in different venues, can’t we respect that?
