Even those get some attention, but I agree that they get a lot less attention than equally armed minorities equally far on the left with similar rhetoric around propensity to violence. (However, note that Antifa got away with / gets away with a fair bit.)

It's not remotely fair that the violent far-right gets a sort of quasi-exception in scrutiny, but you shouldn't count on fairness that doesn't exist when deciding on a pragmatic course of action. You should react to the situation as it is.

The reality is that the states where trans rights are most under threat are very pro-self-defense, and trans individuals should probably avail themselves of that right, but those same states are also very pro-use-of-governmental-power-to-achieve-ideological-goals, so you want to be absolutely unimpeachably clear about what you're doing, not just hoard guns and refuse to explain yourself to people who might misunderstand (but aren't already ideologically committed to misunderstanding).
