Spike is a nasty sexist pig who objectifies women,

I've gotta admit I didn't really see that. There is *something* about Spike on Angel that is off (lighting? directing? acting?) but I haven't been able to relate it back to lines or plot.

I see Spike treating women the same way he treats men, with an equal amount of disrespect - with the exception of Fred who he is obviously soft on. I actually think yelling at that women in the alley was really in character for him and that he would have done the same if it had been someone like Andrew he'd saved (assuming Andrew wore heels)
