I certainly don't think there isn't a road back for the accounts mentioned in the post. To my knowledge, they have not lashed out with horrible, personal accusations, which personally I would find hard to forgive.
Some accounts have been called rapists, pedophiles, etc, and those dishing out that kind of accusation, I'm not sure I could forgive.
I remember death threats against someone's family back in 2017, I think that goes too far.
Yes for sure. It's time to leave when you've reached that level of anger.
