It depends on your definition of transphobia. If your definition of transphobia is hateful comments against trans people, then yeah, sure. If it includes people who want to debate the climate, such as bathroom issues, pronoun discussions etc, then no. That's just censorship and not allowing debate.
Same with GRT, actual racism against them, sure, ban it. But that shouldn't be used as an excuse to stifle discussion around real issues. If a GRT community are illegally camping on land, then that's a crime and it's not racist to point it out.
Like everything in life, it's nuanced.
I dunno, being a CEO is a stressful job, the buck stops with you ultimately. Yes they're paid very well, which counters this a bit!
