In this sense, yes to Reddit and YouTube. YouTube may not be very social but it clearly has an algorithm that pushes toxic content/stereotypes.
And im going to say no on Lemmy. Lemmy may be social but there’s no algorithm pushing toxic content. Maybe I’m missing it but there’s seems to be very little toxic content.

I’m saying the term is somewhat nebulous, with lots of gray area but also an objective definition would not answer the question.
People do disagree on what constitutes social media, and even apply it inconsistently to themselves. So let’s not pretend there is a clear definition. Language isn’t always cleanly defined so we can understand what “social media” is based on context
