It isn't as radical as people think it is though ,but tries to take all the credit for anything in the north. A lot of northerners love Manchester, it's a great city, but it isn't THE north, and people get sick of hearing about it sometimes. More than three quarters of people who live in Greater Manchester, do not live in actual Manchester or its suburbs. Yet on TV and in this thread that's all you hear
Again, this does not pertain to the existence of a radical tradition in the City of Manchester. You really aren't going to get anywhere trying to back your original claim up.
Not sure what you mean
You were talking about how people in eg Rochdale, Bolton etc don't really define themselves as being Mancunians, and the incorporation into GM hasn't changed that. While that doesn't tell us anything about whether the City of Manchester has a radical tradition or not, it's true in itself. However, you left out the non-CoM boroughs where people are more likely to view themselves as Mancunians. Those are in the south of GM.
TLDR, fine to say that conflating Mancunian with the whole of GM is alienating for eg Oldham. And I don't think anyone really understands why Wigan is part of GM at all. But the flipside to that is that the attitude you discuss is not at all the same in Stockport and Trafford, and there's variation in Bury depending on where you are. If we want to talk about attitudes in different boroughs, we don't just do that about the ones that suit your point.
