To tackle this human issue at its root, the like/dislike ideas we falsely believe are the correct way to examine, decode and judge our world are not entirely honest. Our proximity to each other as a group is the problem.
By default, we judge and sentence every life-form we are subjected to, as though that was our purpose. Doing this creates the belief that positive and negative ways of seeing people are right and OK but it clearly isn’t. If we need to think bad of others we should examine what we have been taught and how we have been taught, and what we have been educated for. Like and dislike. Enemy and friend.
