You're not going to get anywhere in terms of left-wing organizing or provocation if you can't accept someone having an accidentally bad take on something or being less sensitive than is necessary. Wreckers and transphobes are different from ignorance or lack of interest (by the way, this is something that occurs in the physical world a lot too, we tend to care about our own oppression more than that of others). You should educate people, not berate them.
