Sounds like your entire argument is based on nothing but semantic and personal opinion as to what true communism is.

Would you like me to cite marx...? These are not my opinions. These are the opinions of marxist scholars... who... defined marxism and communism in the first place?

these aren't arguments they're statements of fact about what communists believe...

also of course they're semantic, all conversations about the meaning of words are semantic??

"semantic /sĭ-măn′tĭk/

adjective

Of or relating to meaning, especially meaning in language."

Good luck trying to change society if you claim ‘But that’s not real communism!’ every each time

What? No, the claim is that they're trying to build it, never that they just magically will achieve it. This argument doesn't make sense unless you don't even understand the claim being made.

Communism is quite clearly defined as a stateless, currencyless society without class division... we aren't denying that without reason? We're denying it because it definitionally doesn't match it, and can't hope to... because of the natural progression of history.

Or learn about what "dialectical materialism" means so that you can actually understand what you're arguing against well enough to actually make an argument against it.
