they need to accept that people don’t understand even the most basic principles of what makes someone trans.

I remember talking to someone complaining about an article supportive of underage people transitioning, and the main thing he was outraged about was based on, he didn't understand that people have different concepts for gender and sex, and so he honestly thought that the article must be talking about bottom surgery and that was the only thing the words it was using could mean. It wasn't just disingenuous rhetoric, he actually misunderstood and accepted being corrected on that.
