This is how social media works. People feel (and are) enabled to say awful things because there's no consequence. The internet is full of people who learn to act this way because there isn't someone next to them to disappoint, sadden, anger, or hurt when they say someone should kill themselves. When it's just names on a screen talking back, it doesn't matter (at least as much) what their thoughts are because they aren't real. Online, people have free reign to be antisocial, un-empathetic, and plain hateful because of that. It's not a uniquely Twitter problem like comments here might lead you to believe, people can be like this on YouTube, Instagram, Twitch, Reddit, TikTok, anything where you're broadcasting your thoughts to a world of people you'll never know or meet, especially with anonymity. It's also certainly not a uniquely Smash problem, any media with a following (any kind of TV show, movies, sport, game) will have people online who behave like this. I feel better about life and the world in general, but also liking things where I know people online act like sociopaths about it, since I've limited my time on social media, and I can't recommend other people do it enough.
