I remain convinced that at some point in a liberal’s life a switch is thrown that results in several phenomena:
1) They fall prey to one, some or all of the seven deadly sins and some others too numerous to mention here.
2) They are consumed with guilt which eventually turns to anger.
3) To assuage their guilt and anger they lash out at others around them, often complete strangers as anonymity provides cover for their cowardice.
4) The anger is often of a passive-aggressive variety which manifests itself in a lifelong resentment of anyone who achieves success without dependency or a rigged system (so-called ‘fairness’).
5) Since so many share their mindset, they constitute a voting bloc. Politicians take full advantage of their misanthropy and use it as a springboard to power.
You just described it perfectly.
