Labour councillor inciting terrorism

Is there some unspoken rule or perhaps a hidden clause in Labour's various illiberal laws that says Labour politicians are exempt from punishment under them?

He had it coming to him eh Flo?

Only a month ago Diane Abbott broke Labour's oppressive anti-racism laws with her statement on Twitter that "White people love playing divide and rule".  Her punishment?  A going over on the internet, some negative press (not the Guardian though, naturally) and ... well, that's about it.

Now a Labour councillor from Sunderland, Florence Anderson, has incited terrorism "appealing to the IRA to find it in their hearts to bomb the next Tory conference" on Facebook.  Her punishment?  Suspension from the Labour Party and ... well, that's about it.

UKIP is often criticised by LibLabCon for being unconventional but I think it's a fair bit easier to justify calling an unelected Belgian nobody a damp rag than racism, inciting terrorism and attacking pensioners.
