I'm jesting, of course. But only partially. I find it unfathomable that someone would embrace the forgiveness and grace of Christ, and then somehow feel justified in withholding grace from others. Like, the Creator of the entire Universe dies for and forgives us. On what logical grounds can we look at someone and say, "Nah, you're too icky for me." It takes a frightening kind of cognitive dissonance to do something like that.
Sayng it's a preference doesn't explain anything and the contradiction remains so it's easy to understand why many other christians and non-christians see some believers as willfully hypocritical, even if it's not the case by intention.
