I don't have much patience anymore for Christians who open statements about the history of Christianity with a denunciation of it, and whose defense of Christianity amounts to 'Well we learned our lessons of the past - sorry again, by the way - and, even if we're imperfect, we aren't nearly as bad as we were. Please forgive us.'
There is a school of thought - a popular one - that suggests this kind of self-deprecation is somehow noble, pure and thoughtful. In a word, I find it disgusting. Also unChristian.
I no longer want anything to do with this kind of person.
