Interesting article. It's easier to hate or criticize those who are not part of your group. It's a heckuva lot harder to do so for members of your group.
Most churches have their complement of divorced members. You look at them every Sunday. How are you going to criticize or hate them.
OTOH, most churches have no homosexual members. It's a lot easier to hate the person who's not there, it seems to me.
Church should be about "us" sinners but it is too often about "them" sinners.
I ran a Sunday school class for a while. I had one hard rule. You couldn't talk about what "they" did. You could talk about what "we" do all you wanted to. Visitors didn't stay very often.
Shalom.
