"A man who won’t believe in God will believe in anything." - G.K. Chesteron
Erik von Kuehnelt-Leddihn, in his magnum opus, Leftism Revisited, made the assertion the leftism was based on the "murder of the Father" and the attempt to overthrow him out of envy.
You can do a lot with that comment. Leftism is almost always materialistic and atheistic. And of course, God is traditionally male.
Feminism is leftist...and oftentimes atheistic (or paganistic). And is based on hatred of men, hatred of "patriarchy," the hatred of any idea of God the Father.
I have for over 20 years thought leftism was based on hate, which they project onto their enemies. It's why they talk about "hatred" so much. It's their hatred, projected on others. One of its tactics is to portray themselves as victims, when in reality they are the victimizers.
Leftism is feminine, specifically the Bad Feminine. The same applies to feminism. Want an example of the Bad Feminine? Try Lilith, Adam's first wife, who murdered babies and ate men.
Leftism is never about equality. It's about power. The power, ultimately, to destroy the Father, and men. It's one of the reasons why women should be kept out of positions of authority in politics and most especially the Church, otherwise we'd end up worshiping some Goddess (and witches)...who will end up being Moloch (like sacrificing babies).
Leftist's ideas have never worked and they are working less and less every day.
