I just want to echo your comment, because that's also exactly what happened to me. Learning about USA interventionism scratched an "itch", made me pause, reflect and conclude: "hey... The USA sucks... They tried to control my country. Why am I still defending them?"
For me, Socialism was inevitable. I owe that to this kind of entry-level facts about the USA that highlight the contradictions of Capitalism.
I totally understand. I avoid these "archetypes" of videos like the plague. But that's the current al gore rhythm. I think this type of content works as a starter.
I also had this initial rapid reaction to the "I had a Ben Shapiro phase" comment, but it's something really common, even I went through this (many years ago I identified as libertarian!), but the content is great because it goes beyond that by bringing up practical steps.
Now that you've put that into words, it kinda makes sense. It's because the conservatives don't see queer relationships as equally valid or serious, even if the end goal is the same. That plays a lot into identity: they identify themselves with their "traditions", which includes "family", so when someone different tries to do the same, "oh, they're destroying 'The Family' by trying to have a family!".
It's kinda like gamer guys™ when a gamer girl just exists: "oh, no, she's a gamer girl, let's pick on her! You can't like the same things as me because of your gender!" In the end, conservatism is all about identitarianism ("you can't do x, y and z thint if you're a Man!!")—even though they'll blame that on the Left, because every accusation from the Right is a confession.
They will crank it all up to 1488%
