At the risk of getting myself in trouble, I'll point out that there seems to be an opinion in some American conservative circles that obtaining book knowledge on a subject dooms one to be a member of some sort of intellectual elite, and there is some sort of virtue in not allowing one's principles to be diluted with facts.
It's not universal, and it's understandable. There are commentators (on both sides of the political spectrum, but I see this more among conservatives) who want to appeal to folk with little formal education, and to convince such folk they are one of "them". To such people, understanding the difference between "homosexual", "transgender", and "transsexual" would smack of the worst type of intellectualism.
Personally, I'm deeply troubled at this turn that conservatism seems to have taken, since it means groups like us are more likely to be targeted, but for now it's the American political reality, and to be conservative in 21st century America seems to mean understanding and accepting this.
