Yes, I agree. I'm really tired of people, online and otherwise, forgetting how to behave like adults.
It's as though they've completely forgotten (if they ever knew) how to have a polite disagreement with someone, without immediately devolving into slurs and name calling.
I'm admin on a couple of different FB groups, including a very large artist's group, and the sheer numbers of adult-aged children throwing online fits for no reason is staggering.
There seems to be a lot of that going around these days.
Argumenting with people that are clearly below you is a waste of time.
