Something like that, or that their brains are only pea-sized and not much goes in there
Liberals brains are wired differently. They don’t really think; they just emote. They are incapable of acknowledging any of the consequences of their utopian schemes. They want what they want, and never consider the costs in any terms. Unlike most normal people, they manage to block contravening thoughts completely out of their minds.
Being a liberal means never having to say you’re sorry.
