Its actually one - Danczuk - and I'd wager the only other one before the next GE will be Hoey.
There is bullying and harrassment with Labour, as there is in every other political party, but how much of it actually exists is unknown. Beyond the votes of no confidence, how many actual instances of it can you name against Berger or any of the other TIG MPs?
As an interested observer, there isnt a requirement to make a list of instances of intimidation. If a LP supporter feels that there is an air of intimidation, then there is. A quick scan through this thread will easily throw up examples of folk/MPs not fully behind the Corbyn version of "Labour" routinely described as Rats, Traitors, Scum, Slimey, etc.
That in itself suggests that if you are not a paid up member of ONE brand of the Labour movement, you will not be tolerated. And that, to a floating, not that arsed really either way bloke, is a throwback to a time the Labour Party exhibited similar traits, and was turned off by it.
It isnt the actual policies, its the baggage.
