How do you survive with a psychopath, manipulative and gaslighting people?

I watched some YouTube videos and learned about narcissists, gaslighting and manipulation. The reactions are somewhat organic now. I’m able to see it for what it is and can drop a little hint here and there to them or the group. I prefer to educate people on what those 3 topics are. Then other people can see and judge for themselves. Basically exposing what people want to be covered up in an educational way so they can’t get defensive about it.
