But i don’t get why none of those showed up in any feeds if they exist. I am very far left of centre (by american standards) you’d think some of the people i follow would share - or non-us media would.

Here are a few guesses:

• You are from Europe, so your algorithm doesn’t feed you that stuff as much. It has to be a huge deal, like this one.
• Americans don’t get in our feed either. I have only mainstream sources bookmarked that I go through and I check every work day to post in a small American Politics community. I would know if it came through and they don’t. You have to subscribe to small sites/blogs that put on these smaller protests.
• Sometimes the protests are put on by people that don’t align with your interests. Not that you’d be against them, but that they’re not “your type.” For instance, maybe it’s put on by the immigration advocates, or the Veterans, etc., etc. That’s why this org did such a great job, they brought everyone together under one umbrella.
