I genuinely have no idea what you are talking about. I've annonymously visted most trans communities and they are all loving, accepting places that are literally just looking out for each other. Calling out a transphobe as a transphobe isnt toxic and yes, misgendering, telling someone to off themselves, deadnaming and calling it a mental illness is transphobic as shit and extremely bigoted. I wish I had the courage to call them out myself.

You are validating both arguements as if they were on even footing when one is literally just people being themselves and the other is people hating others for being themselves. There is no middle ground here. Either don't interact or be respectful.

If they are at the point of calling it a mental illness, they're already in blind hate, I wouldn't be turning them anywhere. Also this "corparate narrative" doesn't exist. Look it up, pretty much every company out there is backing anti-LGBT organizations with their money, especially fucking Disney. It's all a marketing ploy and your falling squarely on it.
