Do you actually believe the left would waste resources trying to "re-educate" anyone known to be on the right? The only re-education we'd get is a bullet to the back of the head.
You are probably right. But as we all know totalitarians do not kill all enemies-—they have Siberia or Chinese labor camps or North Korean construction crew prison work.
And Chinese and Google together are going to a great deal of trouble to see if they can “read minds” by brain area computer scan surveillance followed by memory implantation to indoctrinate the victims. More trouble than one bullet.
But the modern way may be just death to all non socialists. You probably nailed it.
Especially if you get into the Nazi fetish with killing off the old people.
