Yes, he will find that a gathering of right-wingers is less welcoming to gay people than the left is, but he will also watch something astounding unfold. Unlike liberals, rightists, after a period of open discussion and thought, will actually admit when they're wrong and change their minds. This anti-gay prejudice will fall -- it's falling now.So, bottom line, in the right wing mind set, it's better to be wrong and eventually change your mind than to be correct the whole time. It's better to oppose equal rights for blacks, women, gays, and eventually, maybe, kinda-sorta-but-not-really, come around than it is to have always known equal rights for all is a good thing which should be uncontroversial. That, to them, is having an open mind.
They are truly warped.
