Racism, Sexism, Homophobia.

[Anomalocaris]

I think each form of discrimination can take many different shapes, and whether one is worse then another depends very much on what shape each form of discrimination takes. In their more common forms in developed or semi-developed societies outside the middle east, sexism probably does not kill or imprison quite as often as racism or homophobia, so I would say there while they are all not good, they are most certainly not equally bad.
