“It makes perfect sense that such people’s first allegiance would be to our country, and to our people.”
It might seem to, but that doesn’t explain the millions of liberals that seek this nation’s demise including the very president seated. However, the founders knew there would be people that sought to take over the government, to enslave, and to abuse it. They even remarked a revolution once a generation might be necessary to secure freedom.
The Framers were wise. They knew we'd eventually reach this point, hence their remark. I'm sure they'd be aghast that we've endured this extent of abuse without revolting.
