Nice? Nice would be if "government" or "politician" was something every citizen did on the side and all the time, like breathing, instead of it being a profession. What you are suggesting is "slightly better than the worst", but nowhere near "nice" in my books.
Also, for what? So the rest can hide behind them? Because that's what effectively happens. Very little change, very great excuse. We couldn't even discuss police brutality here without some people moaning about how some cop or other is a decent person, as if generalizing to make a point is somehow worse than shooting unarmed people.
Not that I don't hear the point you're trying to make, I used to think that too, I don't anymore. When something is past the point of return, just throwing people at it won't turn it around, it just wastes perfectly good people. I'd rather lean on the assholes who currently work for assholes, to stop being assholes, than send non-assholes into that grinder.
