I had to scroll through over 24 hours of posts before hitting anything political, an article about abortion in Texas. Definitely not the majority of the content and it took way more scrolling than a couple of screens. I still haven't seen anything else on your list yet.
While that guy obviously has an axe to grind, if you visit the main page of that URL there's plenty of tiresome politics all over the place: https://social.lol/ It seems to be coming from different instances, though. I have no idea how Mastodon chooses what content to show on that page.
Gee. When I just go to https://social.lol I see this as the first thing: "These are posts from across the social web that are gaining traction today. Newer posts with more boosts and favorites are ranked higher."
