The problem is that this (if my theory is not just bunk) isn't something you can really go back and do differently. An emergent property of the reactions of polarised groups to the behaviours of their leaders was discovered to be quite different to what had been assumed. You may as well say "we have to go back to the old ways" when lamenting the relativity makes physics too complicated.

Though, as to the point I think you're actually making, it's also been made very difficult to object to these things in any terms that could possibly have an effect without being thoroughly denounced as a nutter, an extremist, or worse. After all, the "right" thing to do is always to simply "vote!".
