You make a great point that the "harassment" is in the eye of the beholder, and that being sensitive to others can be taken way too far.
You also (maybe unintentionally?) make an entirely different and equally interesting point, that also shows another side to gender-bias. You bring up the relevant point that there are double standards on both sides of the gender divide. It's a double-standard that it is not okay for women to be looked at as sex-objects by men, but it's okay if women do it to men. You are right that probably no one would have batted an eye if the comment was made from a woman about a male model. In fact, men would have laughed and thought it was cool. This brings up a different question. Is it genetically inherent and absolute that men and women will always think differently about things, or is it the way we are brought up and the lessons we learn from society?
Also, I loved what you said in your last paragraph, "...the political correct actions took the long slide down into lunacy quite some time ago..." This was hilarious.
Lastly, I still keep coming back to something... even though this really was silly and got blown way out of proportion, why did it happen this way? What in this situation caused all of these other issues to bubble to the surface? Is this the universe/karma/whatever giving us an opportunity to look at equality as a whole and see where there still needs to be some housecleaning? Yes, there is a danger in over-thinking things, but we also don't want to ignore things just because they immediately seem silly on the surface.
Ultimately, I don't really think the comment made about the model was bad, but I am intrigued that the situation inspired me to think a bit.
