I’m sure social media is what’s broken politics. Look at peoples comments on a some YouTube video. I can’t believe what people believe and perpetuate.
I guess people fell for other people’s garbage too but algorithms just make lies spread with a lot less effort and honest people are less inclined to participate in this behaviour.
Having used Mastodon, which prides itself on having no algorithms yet is also home to some of the most extreme ideologies, I doubt algorithms are as much to blame. I think it's mainly a humanity issue.
