Racism is generally regarded as being entirely unacceptable today. The problem comes when you extend this to other concepts.
The way to get round this, surely, is to specify what constitutes transphobia?
Calling someone a 'fucking tr**ny', yes. Saying humans can't change sex and transwomen are men, no.
The whole point of this is how it stops women explaining why the trans ideology is dangerous to them. If you can't use the correct words, you can't explain it.
It really would not be a tremendously difficult exercise to decide what does, or doesn't constitute the concept of transphobia.
Pointing out that sex matters is being called hate. Pointing out the number of men who fetishise women and are advocating for self identification, is regarded as hate.
Tiptoeing around the edges of the debate doesn't work. Fortunately, I genuinely believe that people are getting closer and closer to the centre.
