Never underestimate the 'religious' fervor of leftists - its success is documented. The 'religious' part I'm referring to is their self-righteousness in assuming the moral high ground - they literally worship themselves. That is a powerful force and has enabled them to take over every institution in our land - education, media, government, churches, synagogues, etc etc. Name one that they don't run now!
The tunnel vision - of their minds - enables them to disregard human nature and the laws of cause and effect. Their motivation trumps everything in their life - family, fellowship and purpose in life. They are true believers!
Look up the name Antonio Gramsci - you will be amazed.
