@mrjonno every human society is flawed, that's the reality.
The claim that Marx is somehow out of time gets repeated often, yet if you actually read Marx then you'll see that his writings are very much relevant to our time and what's happening in the world today.
And I have no idea what gbtqia has to do with communism to be honest.
@mrjonno I must also assume that you're entirely unaware that GDR was a pioneer of many lgbtqia rights?
