Lad, you (or somebody, I think it was you) stated that the perp's racist rants proved that white supremacy was his motivation. I said the totality of his comments were those of a nutcase, and that therefore attributing motivation in any logical construct was not possible. Maybe white supremacy was his primary motivation, maybe it was a minor factor, maybe it was the flavor of the day when he got into a rant mode.

As far as the second point, about linking "right-wing" and "racist," that is an argument to which I take great exception. Fascism, nazism, and socialism/communism are all at the opposite pole from classical liberalism, which emphasizes the primacy of freedom and liberty against the power of the state.
