The thing about anarchist politics is that it rejects representationalism (sorry a buzz word I guess). There is no single person or group can represent the whole. This is unlike say traditional Leninist politics or liberal politics where the revolutionary party or the executive of the state can represent the masses or the nation. So Attica whilst representing himself makes no claim to represent others engaged in anti-capitalist or anarchist action (indeed to his credit he makes it unabundantly clear how he differs from them). So it is unfair to judge the large, ever-changing nature of anarchist activity from one or two people (or the odd group).
In short, if you don't like what Attica (or whoever else might be annoying you) is doing, there is a whole lot more which you could introduce your student (male or female) to. Whilst there are some dickheads (and fannyheads), in my experience - limited though it is - I have found anarchist politics to be exciting, life-affirming, amusing and sometimes even effective.
