I think I already pointed out that by 1935 in Germany it probably was too late.
To late to correct that one, yes. But not too late to prevent the next one - that's what I'm arguing about. I'm saying that this sets up a negative bias for doing anything early enough when controversy pops up, which is at best not beneficial.
Yes, indeed. This goes for any course correction, the longer you wait the more extreme the correction will have to be until they are accurately described as 'violent'. The French Revolution comes to mind (not that that was such an example of exclusively positive change but it definitely was change).
Now what do you expect them to do when they're offered the chance to vote for two new candidates, neither of which they approve of? Personally, I expect them to run the other way, rather than voting.
