I hope people get the right message from this, which is:
The way people talk about "Capitalism" is most often silly and counterproductive because most of the time -- the person that hates capitalism and the person that loves capitalism are talking about nearly entirely different things.
Capitalism was a term coined by Marx, so not really surprising that most using it are anti-capitalist.
Also, should we capitalize the "C" in "Capitalism"? One might think we should, because C is a capital letter. But capital itself is lowercase, and therein lies the paradox.
I think it’s productive because it serves to stabilize the society by giving it an ideological underpinning.
Roughly: there’s no better alternative to capitalism and we have capitalism therefore we have reached optimal society.
