IMO, the perception of an extremist mainly exists in the minds of those who are already so extreme so that even a centre right or even centre left would appear extreme to an extreme left winger...LOL
So, your header is wrong. There are some, if not many, who are unhappy with the ABC who are not right wing extremists.
Your untruthful header says "only right wing extremists attack aunty abc".
Why do the left have to keep distorting the truth?
