Outside the swatting, I have seen the same things in my projects. There are always people trying to break me. I never talk about it. I will never do. Because if I do, they win.

The best way is to de-escalate/disarm them. Usually that requires some level of empathy against the attacker to speak the same language, confirm their mindset, let them know you heard them and you are going to do better (even if it is not your fault), propose to leave what was said behind and move forward.

If you truly care about the project and it's mission, you want to minimize damage at all costs. Because if the project wins, you win, regardless of which concessions you made to fix these inevitable situations.
