I think that a lot of goods points were made regarding mob mentality and bullying, etc., and I could comment on all to a great extent. However, I'm going to get back to Shing's original question regarding the morality of this fetish because I believe that there's a lot to consider. I'm not sure if Shing made the post as a means of eliciting a conversation that might help him gain insight into his own feelings, or if he is merely trying to shake the trees to see what falls out. Whatever the case, I'd like to add my two cents.
First, I've always believed there's somewhat of an oedipal basis to this fetish. Virtually every guy who is into fvf has had a strong female presence in their lives; most likely mom, but possibly older sister(s), aunt(s), neighbor women, etc., who were assertive and competitive. One could even argue that the type of fvf that a particular guy enjoys indicates his feelings toward women in general. I have absolutely no proof of this; it's just something that I sense. For example, I think that I can define my attitude toward women through this fetish. I like good competition between two evenly matched, similar body-typed women. I don't even care who wins, I just like the competition and the intensity. I can't stand blood, humiliation or one-sided fights. I wonder about the subconscious mind of those who do.
I have always been attracted to competitive, athletic women. Although Mom wasn't athletic, she was certainly assertive -- and feisty. No doubt, this is in influence. Also I grew up in the pre-Title 9 Era -- there were no interscholastic girls' sports. So, I had to surmise if a certain young lady was "my type." I have always believed that a woman who will physically compete with another woman would be much better in bed that a sterling princess. Again, I have no proof of this, and I would have loved to have conducted my own study on this when I was younger. Perhaps one of you young guys can do so in my stead. If you do, please keep my apprised of the outcome.
Later.
