Well it was, up to a point.
Then he began to quote, with favour, Rosa Luxembourg, and I couldn't continue.
My God! There are still such people around?
Although it's hard to believe, I guess there still are Spartacists and Trotskyites and various other kinds of misguided Marxists.
Regardless of this person's political views though, I thought the article was worthwhile reading. It wasn't at all the typical warmed-over Marxist rant.
Some of these issues have very little to do with a left-vs.-right dichotomy. One's views on terrorism, Iraq, etc., are not necessarily correlated with one's place on the political spectrum. There are some on the left (far fewer than in the past, however) who are thoughtful regarding security issues.
In fact, it is a bit surprising that so many on the left have turned into apologists for terrorists. I think that part of the problem is that their other views have been so demonstrably discredited that one has to ask why someone would remain there. The reasons for remaining in the left are generally a hodgepodge of intellectual dishonesty, emotional rebellion for its own sake, and a nostalgic living in the past; this is sometimes combined with pure power politics. People with that lack of foundation generally have very little interesting to say. But this lack of foundation is not universal; there is some intelligent commentary from those on the left, and I wouldn't want to maintain otherwise.
