I haven't said anything meaningful about politics.
What I said, perhaps a bit too abruptly to be well understood, was "the use of a non-meaningful piece of slang that is almost entirely held by a specific group of poorly informed folks is a red flag that any attempt to discuss politics will end in a likely mix of muh jerbs and dumbocrats."
The phrase "leftist" properly applies to a group of people who essentially haven't existed in the United States in around 80 years.
It would be like if someone went to a baseball stadium and started calling people soccer hooligans. That is not a person from whom to learn sports.
Thanks for the attempt at a table turn. You've been a delight
There are large numbers of people who describe themselves today as leftists, and there have been for the past 80 years. People across the political spectrum, academics, and the news media use the term in relation to contemporary politics.
If you are using a definition that stopped being relevant 80 years ago, it will be hard for you to have a coherent discussion with people today.
