Our entire shtick is trying to believe what's actually true, not on what we wish were true, or what our culture tells us is true, or what it's popular to say is true. If a man thinks he's a woman, then we might (empathetically) wish he were a woman, other people might demand we call him a woman, and we might be much more popular if we say he's a woman. But if we're going to be rationalists who focus on believing what's actually true, then we've got to call him a man and take the consequences.
