Their point is that there's more than 1 widely-practiced religion, and there are plenty of sects that are tolerant to different forms of self-expression. Saying food is bad because you don't like bananas isn't sound logic, and applying that same logic to religion doesn't work either.
I can't speak for any Christians, but many of the religious people I know are some of the most tolerant people I know because their religious schools focused on doing things with good intent.
