Is a car or shirt or house personal property?

Yes.

I reference "dignity" because it's part of "the unshakeable foundation of the Republic of Poland"

Yea, not sure I care about the right-wingers in Poland either.

cooperate with you if you remind them of the Soviet Union, and I expect that saying "we should remove the capitalist class" will do that.

Well, I think we should be honest about our intentions, unlike the capitalist class that tell you "brown people" or "the economy" is the reason they pay you slave wages.

What misinformation am I repeating? I wouldn't have written a statement that I don't think is true, so I suggest you point out anything you think is incorrect and explain your perspective, and maybe share a URL for some more interesting sources.

The part about seizing personal property to pay taxes, for instance. A progressive tax system can have bottom tiers paying no taxes. The right are those who impose high tax rates on the middle class and poor, in order to make them hate taxes.
