The issue which people react so allergic to is the complete lack of tolerance by the transgender community.
If someone points out that a man who really wants to be a women is in principle still a man then they get instantly labelled a bigot. It completely misrepresents the definition of tolerance. Tolerance can only exist in a state of disagreement. If we all agree on something then we have nothing to tolerate. Tolerance is really the act of people accepting that some men want to live their lives like women without actually believing themselves that these men are women. That is tolerance and therefore anyone should be allowed to hold the opinion that trans women are not women but that’s okay because we’re still cool in calling you a female name and complimenting you if you wear a nice dress.
It’s like with religion. It’s perfectly fine to tell a hardcore christian person that you think god doesn’t exist. It doesn’t make you a bigot, just a human being with an opinion. As long as we still let people live their own experiences without fear or discrimination then we don’t all have to believe in the same god. It’s the same about gender ideology. The trans community needs to accept that only because they feel they are something that it doesn’t mean everyone feels that way about them. The vast majority of people have no issue with transgender individuals. They just know that a man with a mental health condition is in principle still a man and we shouldn’t be ostracised to state truths like this.
