Of course the risk of "misgendering" someone is the top concern. Very stupid concept, and frankly, I'm not sure that the Right argues over the verbiage very wisely. When someone says we're "misgendering" them, I hear people like Ben Shapiro or Matt Walsh get into an endless haggle over there being only 2 genders. I understand the point, but I'm not a big fan. If you're arguing over gender, you're already conceding a lot to the gender ideologues, because there's too much subjectivity to that.
For example, I got into a spat on Twitter with a Scottish gender ideologue about a week ago, and as usual, he said I'd be "misgendering" somebody. Well, instead of haggling over how many genders there are, I just told him that I'm not referring to anyone's gender. I'm referring to one's sex. I basically said you can claim any gender you want, but the issue is how others (including the law) see you. I told him I identify people by their sex, not what I think their gender is. It left the guy with little to say.
