In simple words it all boils down to this – if you consider everyone to be like you ( which is a subconscious assumption, for the only thing we can know in another is similarity) hence if your experience led you to love, therefore you think everyone loves ( this is why naive ( liberal) people refuse to admit that there is genuine evil) however the flip side is that if your own heart has been raped ( rape itself as a psychologist told me is not about pleasure ( which people can get for free) rather abuse, and this abuse stemming from jealousy of love has a thousand forms, all consisting of somehow demeaning) hence those carrying this resentment ( for there is no greater resentment than emotional abuse, for just as you would hate if someone demeaned whom you love, as you have/ had self love you hate the abuser) hence you begin to assume negative motives and justify being a bully
