Burning Inside,
LOL, Nice format buddy. If I were you I'd have used it as well since it makes it less likely the respondent will quote you directly in his or her answer, which could only be a plus for you.
You had no point, which is itself the point. Your silly friend made a baseless generalization, which you obviously agreed with yourself. Even in your denials that somehow it is not a personal opinion you share, you go on to reiterate the same dumb point as a good topic of discussion. You even hint that "you could learn" from a lively debate of the issue, then immediately contradict yourself again by shooting down the first poster who dares to do so. It's pretty clear you were not looking for a discussion, but a bitch fest to air grievances against all those "sluttorific women."
Amsuingly enough her one sentence question cuts through the heart of your "friends" ridiuclous point. Since now that it has been pointed out to you ad nauseum that your "friends" limited sample can in no way be said to reflect a general female population, your entire point is now "some women are slutty" with some vague, unsubstantiated, and rather puerile reasoning suggesting that this could be every girl.LMAO
I repeat her question. How is this any different than men? Better stated, how do the actions in any way,shape, or form even come close to suggesting a behavior anywhere near as bad as men.
Lets put it this way. If some hot dancer in a strip bar were to walk through a room of 100 men and ask each in turn if he'd like to have some free sexual favor from her, how many would say no? In contrast how many women in a strip bar would accept a similar offer from your friend? If you don't imagine there is a night and day difference between the two, you have no understanding of women in general, and further discussion is useless.
Back to your point

Some women are sluts, some women cheat. hey, there's a revelation. Women are not the angels they portray themselves to be? How about more accurately women aren't the robots so many men wish they would be. I've dated a lot of women and I have yet to date one that claimed to be an angel. Do most all people highlight the positives, downplay the negatives, and try to portray themselves in a favorable light? Of course. Did anyone really require to be reminded of this?
I suggest you read Werd's comments again. They are not only relevant, they are the point. And in the future reveal less of your character by not being so "defensive" when a woman contradicts you, or corrects an obvious error. You are revealing more about yourself to the reader than we care to know, or you would care for us to know.
