I can't deny that the liberals I know inevitably display deep pscyhological and social troubles. The normal, sincere few who pop up in lonely defense when the mass of their further-left peers gets called out for misbehaviour, to plead for civility and offer the dialogue typically denied to us, I rarely see otherwise. The "cult-like" bias of their information network is a matter of record, and just won an election. Disorder and liberalism are hard for me not to correlate.
Still, personality flaws gravitate toward both extremes, and are secondary to the policy claims that big-statism and para-moral secularism actually hollow out and uglify a society. Even a genius can support Socialist tyranny; even a fool can defend conservative freedom.
