I don't think it's possible to have a significant impact on transphobia on the internet purely via debate and text. I do think it's very possible to have a substantial impact in real life just be being a visible trans person out in public life interacting with people.
A lot of people have never once in their life had a conversation with a trans person. It's a lot harder to weaponize someone's existence when they become a fixture in your life. It also gives you an opportunity to occasionally share some of your struggle with people and educate them in a more direct way, but I think the former is often more valuable.
I'm both curious and personally invested on what their outlook on refugees would look like. I've definitely considered the possibility of having to flee to Canada as a trans woman, but I guess the question is how legitimately I'd be able to enter the country and whether I'd have to go into hiding once I get there.
