For some reason this (I thought harmless) tweet has attracted the attention of hordes of right-wing dimwits who think I'm trying to blame the increase in polarization on them. In fact I've said publicly the left is more to blame:

That is in fact what has happened. Since the 90s the right has moved a little further right, but the left has moved a lot further left.
