It is disingenuous to suggest that anti-discrimination laws for trans people are attempting to legislate away the hatred held in people’s hearts, instead of access to healthcare, public facilities, protections against workplace discrimination — things you describe as having “real questions,” but which are, in fact, the parts of a full and dignified life that bigots would deny to trans people in particular. If you pretend like it’s trying to legislate “thoughtcrime,” it’s much easier to distinguish anti-discrimination laws for trans people from rulings like Obergefell or Brown v. Board — far easier to say “look, those were good, but this particular civil rights legislation is simply unreasonable.”
To platform these beliefs is to afford them a legitimacy they do not deserve. To suggest that bigotry, when amplified, will be in some way countered or reduced is naïve beyond belief. Instead, it becomes easier for bigotry to find an audience of receptive listeners and willing conduits for further transmission.
