There are great yard sticks to this question in theory "I tolerate everything except intolerance. Your right to swing your arms stops when they come into contact with someone's nose." In practice though it's always easy - on every side - to pick out the things we don't like and decide that they're violent or intolerant.
Everyone is tolerant of the things they like - and they ask everyone to join them in that if they like those things or not.
If this was some random trans Rachel from Boring, Oregon, I'd call this a clear case of bullying and say the ban was 100% justified and shouldn't remain, but I think there is a much, much higher bar when the target is a government official or celebrity. But that doesn't change the fact that the entire point was singling out an individual for mockery.
While I'm mixed on the ban, this is a mischaracterization of what they were banned for. They were banned for misgendering a specific person not questioning transgenderism. There is a significant distinction between questioning an idea and targeting a specific person.
