Actually, I suspect most churches have a mixture of both approaches in their congregations. That's probably fair enough: churchgoers are, by and large, human too, and tolerance works both ways. Up to a point.
But where I do get angry is when leaders - formal or informal - bring the worst out of others. When someone stirs up prejudice and hatred, spreading the poison from their own soul to their neighbours. It's evil and it's anti-Christian.
The job of the church is to follow Jesus, to treat people as he did. Simple as that.
