I don't know ... it might be fun to wind up the BKs a little bit and hold a demonstration against one of their shops. It will get them all excited ... "it must be the End of the World if an Anti-Party has come back!"
Most of their shops are in nice places, Cambridge, Oxford, Brighton ... we can give Ilford a miss. Why don't you organise protest day trips and have a drink and a meal in the evening? Of course, if you keep good relationships with the BKs and go back there sometime, I can understand why you would not be interested.
There is no shame in that, BTW, as long as you are open and upfront about it.
Every time an idiot BK starts laying their crap on me, I just transform it into something positive .. like writing a few concerned letters or emails to IPs and VIPs for example. I find it to be good therapy and have discovered that many of them, although they are polite to the BKs, share similar sentiments.
I appreciate why you would be interested in just being able to hang out and speak to other people who have been through the same experiences as you, and empathize with them. I hope that you can find someone.
