I have a lot of experience and I am very LGBTQ+ friendly. I only label as extremists those who push beyond the bounds of, "Everyone has rights, gender is a social construct and you can identify as whatever you want" into denying that male and female are things or claiming that identifying as a woman somehow magically makes you female. The whole, "You can't question what we believe or you're a transphobe" is EXACTLY the same as, "You can't question the actions of the state of Israel or you're an antisemite." It's utter nonsense. Those are both examples of extremism.
