People who hate you are your enemies. Enemies will lie and pretend to be neutral or friendly until they feel they no longer have to. Enemies who haven't been discovered will manipulate you to get you to go against your own interests under many pretexts like "being reasonable" or "compassion".

If you really are a good person one of the hardest things, when you first become aware, is dealing with the uncertainty that comes from judging someone to be your enemy when she hasn't overtly given indications of it. Then acting on that judgement despite knowing there is a chance your judgement could be incorrect.

Life gets much easier when you develop more solid heuristics for sorting people into friend-enemy categories and treating them accordingly. As an example anyone who says "diversity" with a positive connotation is your enemy if you are a White Male. Same with "inclusion" if you are a Christian.
