We're in a war. we need to take as many allies who align with most of our core beliefs as possible. As far as I'm concerned, Peter Thiel never gave a dime to any of these homosexual causes in the last decade. Yes, we disagree with him, and he disagrees with us, but he clearly chose our side for a reason. He knows it will be the end of him and what he is most passionate about and that is building and doing, whereas our side can't enact anti-sodomy laws without violating civil liberties, so he clearly sees which side benefits him most and where he can't lose siding with us.
