I couldn't see any obvious ad hominem in the comment. They are correct in that the anti-nuclear stance of many Greens is often dogmatic to a point where they wouldn't even discuss it if the alternative were a social and economical catastrophe. And I don't think it's too far-fetched to attribute the emergence of that dogmatism to the early green movements.
