Well, on this specific issue, I think part of the problem is the messaging. The trans-equality movement is rife with mountains ill-conceived, pop-philosophy, psycho-babble b.s. on the nature of gender and sex, that is often almost perfectly tuned to antagonize the people who need to be won over the most.

My hunch is that many would be more receptive if the messaging was more educational about the hardships trans people experienced (and that led them and their doctors to believe an incredibly invasive, expensive, and irreversible surgery was their best chance at happiness). Could be wrong.

(That and there just isn't a need for bathroom legislation going either direction - total waste of time - neither side ought be making a big deal about that sort of ineffectual legislation which is nothing but pandering one way or the other)
