If ten million people believe a stupid thing, it is still a stupid thing....and illegal. I know some people who are Christian that have no problem with catering to Gay events. To them, a sin is something between God and the alleged offender and they do not allow themselves to judge other people, which by the way, is true Christianity....not this cultish crapola being passed out the the evangelical fundamentalists and southern baptists.
I could care less how stupid you think it is... It's only been common among Christians for the last 1950+ years...
The First Amendment is law.....
