Liberalism is popular among the uneducated and unqualified.
They may go to college but if they obtained a degree they expect everyone else to pay for.
They aren't conservative because they would have to have something to conserve. They demand to share other peoples wealth and assets so they need not lift a finger.
They decry the environment or other whimsical ideals. They expect everyone else to pay for it.
The worst is a liberal with actual money. They use it to destroy and not to build.
They usually want more weed or booze. Very unhappy individuals.
The interesting transformation is a liberal who actually starts to earn money. Amazing how they finally see taxation is theft and all their "friends" expect them to share. Their eyes finally open.
So we can't eliminate this cancerous ideology, but we can keep it at bay.
