A really good guide to being an activist in general:
One of the most important things that trans folks need to get before their arguments can work well is that we tend to get pushed pretty hard to the political left when we come out and transition. It’s not some brainwashing thing—we just tend to be poorer, better-educated, and get hit with the shitty side of our capitalistic social structure, all of which pushes voters toward more liberal or leftist political positions. Given that we tend to hang out in groups, particularly online, we get hit pretty hard with the echo chamber effect, which reinforces socially-common political biases through self-sorting.
In simple terms? It means that by hanging out with a bunch of other trans folks, we tend to get entrenched in political stances that are common in the trans community. It’s the Fox News Grandpa effect.
And I’m guessing that it makes you feel a little uncomfortable to hear that.
This is the first and most important thing you need to face if you want to persuade people outside of your social bubble effectively: you are not immune to persuasion or propaganda. You have absorbed a lot without noticing it over the years, both before and after your transition. And those things? People have noticed them, and noticing those things has colored their view of you as a person and a rhetor.
Put a different way: if they know you have a history of arguing for what they see as hard-left stuff, stuff they think is a bad idea, they’re going to treat other things you argue for with a degree of pretty understandable skepticism.
