Leftists are glad America is dying. Hate comes from envy, and so does war. The root cause of war is not religion, but religion makes for a more difficult opponent. Christians have a winning competitive advantage in life, they tend to have more successful marriages, more children, live in bigger houses, drive bigger cars, live longer happier lives, do better in war, sports, and business, and leftists utterly envy them for it. Left unchecked envy matures into hate and violence.
Leftist envy also hates the 10 Commandments which deals with various aspects of envy; including envy of God’s power itself. Envy must be the cardinal sin of mankind. It is also the trump card in the DemonRAT’s playbook (the Race Card for one).
