> Is it not clear at this point that the real issue is how lacking the term "social media" even is?

It's very clear. Empirically a common sign across all social media is basing very strong opinions on very vague personal interpretation of something that that will forever stay unwritten so it can't be challenged. Anyone can just cement their claim to eternal correctness by ending a personal opinion with some outrage bait like "anyone who doesn't agree with me is tiresome".
