Atheists (and other similars) have the muzzy idea that "tolerance" is good, and "diversity" is good. So they say they believe in both. After all, they certainly wish to be tolerated, to say the least.
But then — as we've seen in metas right here in BibChr City — those same people turn around and tell Christians they shouldn't actually say what they believe, right out loud, in public. They surely shouldn't vote it, do it, live it, let it be heard in the public square. And as the dialogue continues, one gains the impression that they're really not comfortable even with allowing the thinking of such contrarian thoughts as the Biblical worldview creates.
So, as I've said: go be a Christian in church, in specially-marked neighborhoods, at low decibels.
Just not in public — as Robert Knight further documents.
