There's an interesting tension here between legitimate outrage at the nature of their views and the equally legitimate intention to make positive steps towards reducing the impact of those views.
I agree (from a professional standpoint) that there is significant potential benefit to early intervention here, despite the inherent problems associated with identification and stigmatisation of social deficits, but on the other hand from a more human perspective it's hard not to find the views expressed revolting at the very least.
There's a temotation to go one of two ways, to condemn utterly or to pass responsibility rather nebulously into the ether by claiming they are simply a product of society. Neither by itself is useful, but one thing that's clear to me is there can be no defending their views. There's no middle ground where they have points worth considering and the fact that they are seemingly being given some validation by virtue of parallel interests with the current political mainstream is not only dangerous, but also at the root of much of the anger some of us are expressing here.
