There has been a mass propaganda aimed purely at hitting their self esteem by portraying everything they identify with as toxic. Young kids growing up seeing this all around them will internalise this.

Once you had destroyed the self esteem of someone and made them insecure, its very easy to manipulate them into doing whatever you want.

But of course it goes without saying that the blanket statement is not true for all Whites, just mostly those who are more prone to propaganda - those in blue states, those in higher education, those living in big cities and exposed to more Elite environments.
