Why are some women uber feminist?

I love drawing. As a guy what do you think I'm going to experiment with at some point in my young life? >.> Girls! Here's the story. I drew about 20 to 30 pictures in my book and a variety at that. It consisted of Animals, dragons, funny comics, Big Core, Sonic, sculpted, good looking dudes(not gay) and other stuff that interests and/or challenges me. I finally drew a girl and did it FREEZE OVER HELL!!!! It was a serious looking aviator girl that looked as good as my dudes. She was toned, thick, and had a nice chest. Sound raunchy? Well, her outfit was a shirt that did not expose anything but her forearms and flat belly. Her pants came down to her knees. She had on steel toe boots and goggles around her neck. I did not exaggerate any inapproriate body lines or any "details". Her was not part of the picture. And her pose was simple and bold(leaning on her fighter craft). I presented it for my art homework and the feminist girls FLIPPED THE HELL OUT! Why!? When they see a steaming hot sweaty anime guy I draw(again...not gay)they giggle and practically drool over it. I draw a girl: "Womanizer" "Pervert" " addict" "Objectifier". I don't get it. Are guys not allowed to draw beautiful women if it's appropriate? What'd I do?
