@DialMforMara evidently it means "to put your beliefs (particularly socialist/communist beliefs) into practice". it's just a bit of jargon, to say that a thing or person has good or bad praxis based on how their beliefs manifest into actions
@DialMforMara @typhlosion I use it in religious/spiritual contexts to talk about "living faith" as distinct from "having faith." In olden days, I would've said "walking the walk and not just talking the talk," but for once the shorter word won out over the bulky phrase in my vocabulary.
@typhlosion Interesting. I'd heard it associated with "Silicon Valley types", with whom I do not associate socialism :P
