The belief that somehow American Christians are outnumbered, under siege, and fighting for their freedom to practice their religion is extremely insulting to Christians elsewhere in the world who are actually being persecuted.
It's also insulting to non-Christians in this country who have had to put up with prejudice from Christians.
Well that too, but looking at it from a Christian perspective, they really need to stop whining about their own "persecution" and care more about Christians in say, the Middle East.
