This is unironically a very good point.
The intolerance that many trans-rights activists show to those who don't accept that a man with a 'female gender identity' is a woman is similar to the intolerance that many followers of Islam show to non-believers.
No-one on the gender critical side has been beheaded yet, but there is a surprisingly large "kill the terfs" movement that parallels the extremism of Islamists.
