"When you look at all the flag-waving and "America first" stuff, it really sounds like nationalism."
Tell me, what is wrong with love and allegiance of ones country? Every country exhibits their allegiance and love for their countries by waving their countries flag.
As an American, you should want your country to come first. Unless you have had your mind poisened by college professors or public school "educators".
A strong America has been a blessing to the rest of the world. There are millions and millions and millions of people alive and relatively free in other countries because of our largesse.
"To be honest, I can't really think of examples of strong social regimentation coming from either side in America."
Really? Right now, the Dems and some Republicans are trying to force us to stay home, wear masks, and obey, or by God, they will fine and or jail you. It has happened already.
"The Nazi party had the word socialist in their name yet persecuted communists. Kind of like how NK has democratic in their name, but they're anything but."
BINGO!!! Exactly!!!! Totalitarian regimes use the words "Socialist", "Democratic", and "People's Republic" to fool the gullible. It all leads to street violence, secret arrests, concentration camps, and mass genocide.
