Not only scoff at the idea, but often discount it as completely invalid because while pointing out the flaws of our current system you didn't also spoon feed them years worth of theory breaking down all of the potential new systems and produce a dissertation for them detailing every single step from pre to post revolution.

They never look any of these things up themselves of course, because they don't actually care, they're probably just comfortable enough under the current system to believe that they have no personal reason to fight it, and don't like their cognitive dissonance being challenged so making up reasons not to listen or really make any effort at all is easier.
