Ya, in retrospect it does read as overly cynical and yelling at clouds in a way, I agree with that point. My comment captured more than I intended, but the civil rights example pretty much seems like a defining use of the term. Specific, tangible outcome, targeted, not trite at all, connected to a real oppressive issue of the time, but I can imagine people trivializing them at the time.

While I can think of examples that I personally think are a bit silly, I'd agree it's not really a useful contribution.
