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.
