But seriously, what is it with this infantile phrasing?

Well, yes, I suppose it is “OK” to be angry about capitalism, though if you’re a lifelong politician, i.e. unskilled labor, and “capitalism” has still seen fit to reward you with enough wealth to own three homes and avoid working for a living, it might be “stupid” to be angry about it, but I digress. Point is, why is this being framed as having permission to have feelings? Is this yet another instance of therapeutic jargon leaking out into the real world? What can we do to quarantine these freaks and their verbal pattycake-games?
