You have misunderstood my use of that term. Whatever the actual cause may be, it can be found wherever societies exist. That is my point.
My point was was that self-hatred is very rare except among leftists who seem to almost always exhibit true hatred towards the people who sacrifice to raise them and support them.
And self-hatred may be the wrong term. They do not hate themselves. They tend to be egotistical and in love with themselves.
What they hate is the society they live in and the people who support them.
