First, they will tell you.
Second there are two marxist types.
One will usually be the wealthiest lamenting the plight of the homeless and the whales complaining that their tax credit for their “free” solar system is delayed.
The second is the college educated blue haired violent loser who has adopted “queer” as an identity as an excuse for their failures. Then, they will demand the government provides them everything while complaining the government is too powerful.
My first day of college I walked out of my dorm room and saw the guy across the hall for the first time.
I walked up to him, looked him in the eye, shook his hand and introduced myself.
He gave me the Charles Manson stare and announced “I am a Marxist”.
The year was 1970!
The crazies have been with us a long time.
Immediately. They’re like vegans and atheists that way.
And they can interject their politics into any and every discussion, no matter how innocuous. And they will do so if you let them.
I avoid them like the plague.
