The modern progressive movement is an existential plague driven by immense psychological rot.

Leftists are consumed by an intoxicating blend of pride and arrogance, believing their Ivy League credentials grant them the right to re-engineer human nature.  - Bill Brindley

This vanity blinds them to historical reality. 

• Throughout history, from the Jacobin terror of the French Revolution to the starved landscapes of Bolshevik Russia, the intellectual elite has always paved the path to tyranny.
• Today, these low-IQ progressive ghouls look down upon God-fearing, hardworking patriots with supreme condescension. 
• They suffer from a profound delusion of moral superiority, yet every single policy they touch collapses into immediate ruin. 
• They possess an absolute deficit of wisdom, replacing empirical truth with trendy academic theories designed to destabilize Western civilization.

Leftism is simply codified envy. 

The entire Democrat platform relies on mobilizing the base passions of jealousy and resentment against productive citizens.
