“Can no one outside of conservative America think anymore?”
Yes, they can. They think conservative Americans should be murdered.
Thinking and saying are different than doing,but rational and civilized people do not think nor say such things.
The Soviet Union would put people in labor camps for 25 years just for being near someone who is alleged to talk against or deny the Communist platform and Mother Russia. It was quite possible to be disappeared and a bullet to the brain was the ultimate penalty. I believe the left in this country is quite capable of this given the opportunity (if they abolished the Second Amendment).
