Yeah, i kinda agree with you, social media violence is "not" violence, or at least a lesser violence. This was my point : trans are the target of true violence, while being tired of hearing about them is not being target of true violence. This asymmetry may be the cause of that much people disagreeing with you.

On the up/downvote origin, you are right, i did not knew it. Everytime i have seen it used, and so everytime i used it, it was as a like/dislike option. You genuinely are the first person i see complaining about it, so i considered you wrong on this, my bad. But the idea still remains in a different way : though you are technically right, maybe you still can consider that using up/down as like/dislike is a common thing to do.

On the Facebook point, i do not know. It is rather a "like" system than a "like/dislike" : there isn't really a way to disagree with a statement (the "angry" emoji being the closest, but it just conveys that you are angry, not if you agree with the com or not).

Well, let's take it as a personal opinion then. Now here's mine : people seeking attention by complaining about supposedly attention seekers are double losers, first because of my judgment, and second because of their own judgment.
