I can get my head around "left" or "right" wing as broad concepts about economic and social structures, but when you try to pin them on specific points of view, as Steve does, it seems to get more complicated.

Steve suggests that "Standing outside an abortion clinic harassing women and their doctors is positively fascist. " OK, but what about harassing scientists who experiment with animals, or fox hunts, or badger culls? It appears to me that most of those would identify themselves as being on the left rather than the far right.

It's not difficult to think of a left-wing regime which built a wall dividing families, or which imprisoned millions. Or which persecuted gays.

It's difficult to apply these labels to very similar forms of behaviour, and the danger is that you apply them according to one's own prejudices.
