If you want to make progress in USA you must separate the crazy left from the moderate left, if you defend the people who want to ban private medicine then you aren't going anywhere. Those aren't your allies even if they pull in a similar direction, even if they sit in the same party in the two party system.
That is what it implies, there are many in the world who want to ban for profit healthcare and end pay discrimination between jobs. Nobody would ask that question in earnest, its just a rhetorical question to make a point.
