I left it around the time Covid started for that very reason. So much cruelty and animosity.
And I agree with Deuce that social media does more harm than good. Which is a shame, because there's so much positive potential. I have personally tried to be better at not posting things that just stir crap up. I have to remind myself that no one's mind is going to be changed by a social media post, so why bother? For the most part, I post things that I find funny and that's about it.
As for the topic at hand, it's hard for schools to communicate or promote these days without social media. I don't see that changing anytime soon.
