It's not just Jewish space lasers. She liked comments that discussed putting a bullet in Pelosi's head, about executing FBI agents, and replied back about hangings of Obama and Hillary.
If you or I did that, we would be visited by authorities and "our jobs" (as a Congress Rep, a CEO or a store clerk) would/could be disrupted. If the story got out, you could be warned by your boss/employer, demoted, transferred, fired, chastised/scolded by your fellow employees, etc, etc.
These are indirect death threats. If anything, it leaves fear in people's (fellow employees) minds, that this individual is not normal, and may decide to go "postal" one day (especially when you know the individual is consistently carrying a gun at their side).
Yeah, death threats and violence are almost about the only kind of speech that should carry consequences. I thought she only had said stupid stuff like full belief in QAnon and the Jewish space lasers thing; not outright threats.
Tbh I still think that removing her from assignments is not the way to go. If she is such a big threat to her own colleagues (like Pelosi or Cori Bush, who she has apparently threatened as well) that she can't be trusted not to shoot them at some point in her tenure; I still think she should be outright expelled for those threats; removing her from commitees doesn't really do much to protect the safety of the other 434 representatives.
And it must be made clear that she is removed not for her opinions (like I said, she can talk about Jewish Death Stars all she wants) but rather for threats to her own colleagues.
I am not sure how things would work in the US, but assuming things work in a comparable way I guess the vote should not have been on removing her from commitees, but rather on removing her parliamentary immunity. If successful, then she should be sued for death threats, and if found guilty, thrown in jail for a couple of years.
