I'll ignore the fact that now you've started comparing crossdressers to arsonists. You do know that many cis people compare ALL transgender people with perverts, right? By the way, the answer to "Are you an arsonist?" is still a calm "No."
I'm not punishing anyone here. I'm offering my opinion on what it sounds like happened, in order to find a solution. I go to Fenway Health. Everyone there is gay, lesbian, or trans. The patients, the doctors, the financial officer, the janitor. There are big women with beards, guys with tiny hands and curvy hips. Folks of everyTG stripe. Blurting out anything, anything at all disparaging there about any flavour of TG person would be a major faux pas. It's something a cisgender person would do...or someone who had internalized transphobia.
She's going to have to go back through this process, I'm suggesting a different approach. It sounds like you're urging her to do the exact same thing again.
