I treat every instance of someone uttering the word "capitalism" as an indicator of Shitlib indoctrination. There is zero reason to ever bring it up, otherwise. It's a 100% reliable shibboleth for someone who thinks you can litigate away human flaws and force money into the hands of people doing nothing to be worthy of its value; that you can "fix it" with enough lectures and theory. It's either a child who would never know what they're talking about, or an adult who should know better but has been wholly insulated from the consequences of their terrible belief system.
