Montana Republicans aren't just upset that Zephyr encouraged her constituents to exercise their right to protest, but the issue behind the protests as well. The GOP is trying to criminalize gender-affirming care nationwide, which is why they want to silence any opposition to their anti-trans agenda before it can gain public traction. The Montana House is violating both trans rights and freedom of speech all in one fell swoop.
Zephyr violated the House rules not only by encouraging protesters to interrupt an official floor debate but also demeaning the state government body through slanderous and vile personal attacks against fellow lawmakers. If you claim to be fighting for democracy, you shouldn't encourage mobs to disrupt floor debates between democratically-elected officeholders set to vote on an important issue.
