While not too hip on the Gor thing, let me give a little feedback here...
Because a very high percentage of men will do whatever it takes to get a trophy girl ... plain and simple. I'm not saying ALL men, so lets get that clear ... but it's such a high percentage, that hot girls will always get what they want, because they will always be able to find some guy willing to give it to them.
...the hottest girls would end up slaves, or even semi-submissive free women ... the hottest girls would end up being these helpless little sex objects ... men would look at them with aloof detatchement, until it's time for sex.
I don't know whether or not these statements are accurate or representative - I do know that it's a fantasy setting, and to its adherents, a philosophy. That means it's going to be different from Earth, and probably different from your philosophy. So, y'know... calling it unrealistic, I guess that's true, because... it's based on something that's not real, just like Star Trek. (Star Trek is based on many things that aren't real, in fact!)
But if the adherents to the philosophy are enjoying themselves or fulfilling some need, does it matter? It's still probably a fun place to play in, and anyone will tell you that a "modern Gorean" can be just as polite and civil towards women as any vanilla man. So why are you taking offense? If WIITWD was based on a thousand-year-old manuscript left by a mad monk who also described elegant stringlike monsters, each a thousand strong and tangled into a knot of snarling, hissing malevolence, would that somehow invalidate dom/sub relationships? Let's bring the metaphor closer to home - if it also stated that our individual temperments (master, slave, dom, sub, etc.) were based on astrological signs and the phases of the moon, would you be clamoring "The Problem With D/S... I know a Sagittarius who would never wear a collar!"
Speaking of the topic, that's what it comes down to. "The Problem With Gor"... why do you think it's a problem? And is it not possible to be more diplomatic, "One Thing About Gor" or "Something I'm Wondering About Gor"? This thread is going to devolve into snarky snips fast because you're approaching this from a position of rude disbelief and others are going to approach it from a position of annoyed reproach. Nothing productive will occur here. So why'd you post?
Yes, I am Gordon Freeman. Accept this, and move on with your life.
