Not sure I understand your point. Are you asserting that anyone who argues against capitalism as a system must be doing so from a position of ignorance?
They're asserting that someone aggressively arguing against capitalism while freely and wholeheartedly participating in capitalism has some dissonance to reconcile.
I've got a hard time taking an "I'm allergic to capitalism" tweet seriously coming from someone who 1) lists all the ways they participate in capitalism in their profile and 2) makes this statement in the context of their job which depends completely on capitalism functioning.
