Debating schematics is not going to change what those organizations are.
I'm not giving it any sanction whatsoever because it's not what they're saying openly in public, because they won't argue for Marxist ideologies out in the open, but what they're doing behind the scenes I suspect is a vastly different story.
So they're secret Marxists who are in fact, so secret that there is no evidence of them advocating for anything Marxist.
We all know what these organizations wind up being given the history of Marxist/Stalinist political Ideologies.
I know, after 30 years of Social Democratic administration literally every Austrian with money has been brutally murdered after being sent to our Alpine Gulags.
You should just take a look around here, it's a total wasteland here, everything's broken, people eat one another because our Stalinist regime refuses to give anybody food, and roaming squads of Antifa kill everyone who questions our Dear Stalinist Leader.
Don't trust our state-run television channels or the channels that are forced to pretend they are privately owned, who will claim that our country is one of the wealthiest in the world, they're just broadcasting fake news to cover up the Marxist conspiracy that has torn our country apart!
That was sarcasm, by the way.
It'd be like asking if Trump/Republicans are openly arguing for Fascist ideas and have you read Mein Kampf?
See?
Two Can play that game.
I have in fact read
Mein Kampf. Before I went in a different career, I was training to be a history teacher, and a good chunk of my studies consisted of research into Nazism and Nazi crimes.
I could point out several fascist ideas that Trump has been openly argueing for, from overt attacks against Hispanics, Black people and migrants (the classic racial scapegoating tactic that the Nazis had used on Jews), to putting non-White immigrants into "detention camps" (this is how the KZ started out as), all the way up to threatening to unleash the military against BLM protesters.
If you give me a few days, I could supply you with plenty of evidence for these if you don't already know what I'm talking about.
Let us also stop for a moment and reflect that you seem to think that
a) calling Trump or the modern Republican Party "white supremacist" is unwarranted (and that you are apparently unaware of any evidence in support for these claims), and
b) that it is excessively onerous to require someone to back up their arguments with facts, and only something to ask of a political enemy.
