These people don’t go to an existing communist country, cuz the think there is a “ground floor” they can get in on and be overlords who DO NOT have to adhere to communist policies- sad for them. They are just as expendable as all the property owners.
I have repeated you post as you are exactly right. Radicals are very intolerant of other radicals once they have power. Even the smallest dissention will be met with a crushing response. All radicals think they will be at the top after the revolution. They do not realize, as you say, that they will be dead.
