There's more discussion than I ever remember about things like conflict resolution, transformative justice and accountability within the movement. I agree those debates and processes haven't yet brought about a huge amount of success but the discussions are taking place - and this stuff is really hard, solutions aren't going to appear overnight.
I guess I'm just very wary of a kid's today type analysis. There are problems now, and there were problems then, and some of the problems now might be a consequence of the problems then. As an example we're all looking back and cringing on the Russell Brand threads. The movement was not without those attitudes and certainly in the broader more subcultural scenes that anarchist politics was enmeshed with sexual assaults were swept under the carpet, misogyny, homophobia and transphobia were commonplace, predatory behaviour was overlooked, there was little thought given to the dynamics of race in a movement that was overwhelmingly white. And whilst none of these things are fixed, it's worth considering how much of the rise in identity politics came about as a reaction to some of those problems.
