Banned once in 2023 for toxicity and definitely subtly warned since then to knock it off. Two warnings on the tracker although one of those was very slight and the other culminated in a weeklong ban. A definite level of disrespect for staff handling these various outbursts, however, is noted.
...at the same time, one does try to see the good in their users, and in this element of the situation I would agree with Propellus that this is a matter of extremely impassioned arguing resulting in a critical meltdown. I do hate to punish people for pursuing what they truly believe in, but then there cannot be total immunity, either.
Her last formal warning was in mid-2023, we are now swiftly approaching a year since then. It seems likely that similar behavior has occurred since without being reported, but even still, I am in favor of some level of leniency. Only once. I would also find a short ban (2 weeks to a month) to be a stern but reasonable conclusion.
