I can’t exist in any social space without people targeting me

I hate how every time I think I found a social group or space that’s accepting and has good people, inevitably someone there ends up targeting me in some capacity, and they target me selectively too. Even if everyone else there is nice and seems like they have my back there’s always one predator who ruins it and I end up leaving before they can screw me over even more. Recently I picked up some martial arts training just so I can feel a bit more able to defend myself if the situation calls for it, but I mostly started because I felt unsafe in a different social group. It just sucks that everyone has to be so cruel and that these predators hide in plain sight and I’m the only one that notices them. And then if I react or stick up for myself they turn it into MY fault; meanwhile everyone else gets off scot free and never gets targeted. It’s easier to be alone.
