"And what excellent material are women for building a totalitarian society! Their capacity for blind faith, self-sacrifice, leader worship and snooping makes them ideal true believers. What a picture: an elite of intellectuals served and guarded by an army of amazons." - Eric Hoffer, Working and Thinking on the Waterfront.
Let's be more specific. Many women are of totalitarian/fascist nature, their self-sacrifice is for bad causes, they worship terrible leaders and they snoop on innocent people. In other words, they lack discernment and often can't tell right from wrong.
Not only should 90% of woman not be allowed to vote, single or divorced women should be allowed to vote at all. Ever.
