To start with, from the RW side:
Essentially, any disparaging variation on “Democrats”
From the LW side:
Essentially, any disparaging variation on “Republicans”
And . . . that’s about it. “Teabagger” might be in poor taste but is not idiotic. “Teahadist” is just too kewl to be idiotic. Any use of “bigots” might be a real subject for debate and might sometimes be idiotic but does not by itself brand the user an idiot.
Godwinization is sui generis.
“Fascist” is probably idiotic-by-default but does not, by itself, constitute Godwinization. But it’s always a mark of idiocy, and dishonesty too, when RWs use it to describe anything on the left.
Anything I forgot to list?
