I know history far better than the average bear. It teaches me to never say never. Be as embarrassed for those wiser than yourself as you want.
Politicians are on record - including in memes here - saying basically, "you idiots dare to think you can stand against a government confiscation? You think you have nukes too?"
Yup, that's what they actually said. And they meant it, too. Should have been shamed from office for even saying that - but obviously weren't.
Democratic candidates went on record saying they would seize. Hillary said the same, but being slightly cleverer, not as directly.
If it doesn't happen, it's because they still definitely want to but have read the numbers and decided not yet, not yet. But honestly, dead people mean nothing to politicians anyway.
I don't plaster Molon Labe on my car. But I do believe in it.
