I dunno, I just don’t think anyone should, although I get the appeal, join a Left party and spend their time activising for post war social democracy, with all its horrors (and there were quite a few), and i don’t think in a globalised world, where Britain is a somewhat smaller player than it was, it’s even on the cards (I may wrong). And as has been said, think of who you’re going to be spending your time with.
There limits and issues when it comes to doing case work or other forms for solidarity for individuals (including, sadly, that some people are piss takers), but there is quite a lot that needs doing atm. Sorry not trying to sound rude but there are better and worse ways to use your time.
As things are as bad as they and as they’re going to get worse I think it’s better to focus on the tangible solidarity and collective action at the ground level, it’s not just needed (and more enjoyable than joking the Party) you get to pick up on ways of resisting and organising that you otherwise might not: eg there’s a lot of people in my area who are being hassled to ‘move on’ from their social/supported housing into either an even smaller flat or somewhere with less support. Not the worst thing hapenning stm of course, but still a bit shit, still driven by the class war of the ruling class, and it’s not being appreciated. We’ve had quite a few successes of getting the respective providers to fuck off (always on a case by case basis, but they do add up, bad you can start to picture how this might be scalable). I’m not trying to peacock, i just have no desire to join any left party at this stage, I wouldn’t have the time to be doing what i think is useful activity such as this modest housing rebellion, and I know full well that politics that would be advocated by such a party would have all those rebels put away somewhere (and please let’s be honest about that)
