That's an extreme view, tho it may depend one's definition of 'liked' and of 'not caring if one is liked'. As most everyone acknowledged in
@Larry67's thread about the acceptability of disliking some people: We can neither like or be liked by everyone, it is human nature---if we are being our authentic selves. And it begs the question: How many people 'liking' you, by your own definition of that word is enough for you to feel validated?
There are people who fall short of being psychopaths but i still don't care to associate with them or want them to like me. Some in fact, I'm quite gratified if they don't and would do some soul searching if they did. Some would label me an introvert because from early childhood i have been a.loner, and at most could count one hand the number of non-family members who liked me. And i've always been fine with that.
Who doesn't like me can say as much about them as it does about me, and my not liking someone can say more about me, than them.
See to me one of the perks of getting older is not having to care (for familial, or employment related reasons) what anyone thinks about me. As long they don't take any hostile actions against me, i really don't care.
