I remember back in the day sitting in meetings with people so off their face they could barely speak. I might even have been one of them on occassion. Let's not pretend this is a new phenomena, it just looks a bit different because times change.
And it's no real surprise that people who've had a particularly shitty times of things might be drawn to a movement that seeks radical change. How to manage that is probably a fruitful discussion, dismissing it as just identity politics probably isn't.
To the first yes, and it's the same with alcohol, but that's very different to what I see now with some of what's going on with the way some people behave, compounded by social media and other factors. A pissed person in a meeting disrupts that meeting, and can be thrown out. Someone playing shit out on Twitter can disrupt whole movements and groups, and cannot be thrown out. It's not just a question of, 'Oh this has always happened, it's just a bit different'.
No, it's not a surprise, and I'm not blaming them for being unwell or traumatised, but IME there's a bunch of people that aren't drawn to it as a vehicle for social change (or if they are it's in theory only rather than being engaged as such) but are drawn to it as mostly a subcultural space where they feel welcome. And on some level that's great, but that isn't what revolutionary politics is primarily about and we/movement/groups have shown we
can't manage it, and so I think it's partly contributed to the destruction of anarchism as any kind of serious potential social force in the short to medium term.
It's partly the tensions that's always existed within anarchism around personal/political etc. but it's also reflecting the mess that much of society is also in with various collapses and breakdowns in all sorts of social and political areas, just in a particular political scene that is much more vulnerable to this stuff than other similar areas are.
E2A: I wasn't dismissing it as identity politics, I was saying that scene has brought a bunch of people into anarchism with some of them having those behaviours. I think poor behaviour has always existed in the anarchist movement (of course) but the way it manifests itself now (around issues of identity and also predominantly online) is very different and has much wider consequences.
