Social media induced blab - meaning of "not liking" someone

Thank you. Growing up I also didn't really understand the concept of "not liking someone" (worded as a whole person) the way people so often applied it. It's easy to get not liking someone as a whole over doing something heinous (whether others see the heinous part or not, ie intentionally hurting someone like bullying even if others don't see it or you can't prove it). But everyone has idiosyncrasies and also strengths. I don't want to be around some people because of their idiosyncrasies including if they are mean sometimes, but unless they did do something really heinous that's all it means. It means I dislike their weakness enough to not want to be around them, not that I dislike them as a whole person. Because of this I thought maybe all these people just weren't telling me what happened. I have now figured out that not only is a difference or idiosyncrasy enough for most people to straight up actually dislike a whole person, but to their credit a some of the times little things actually are signs that there are future things we should protect ourselves from. (Though I stand by just not being around them is enough rather than staying around them unnecessarily but acting like you don't like them).
