But passing is often as much a mental act as a physical one.
I understand what you're saying, and I can see where you're coming from, but I just think it would be far too harsh and arbitrary to say "I don't think you pass, I don't think you stand a chance so you might as well throw your dreams of being yourself in the bin because the rest of the world is only going to tell you the same thing I am."
I mean, you, I, and everyone here aren't the sole 'Agent Of Judgement For What IS Beautiful'. No one can speak for everyone. Beauty is subjective, both inner and outer. And whilst you may hold one set of views, someone else may hold an entirely different set. And anything you advise someone of is based on what you believe to be true. "You MAY look like what I consider to be a woman if you do X, Y and Z."
I don't believe people to be so gullible that they blindly accept everything they are told. I suspect that if someone doesn't think they pass, no amount of anyone telling them they do is going to suddenly, and miraculously change that. People do have minds of their own.
However, it may let them think "wow, so there are people out there who are kind-hearted enough and caring enough to make the effort to make me feel good and try to help my confidence levels... I'm not alone, I don't have to do this by myself, and those times when I feel down I can turn to my friends for a shoulder to lean on and to feel good about myself again.
It's not so much about what you say to someone, it's why. Motive and intent.
I think that a forum based solely on your model would be equally harmful and detramental to progress because if people got consistently told they don't have a prayer, no one would even try. So, a healthy mix is good.
I think that sometimes everyone wants to, and needs to hear they're beautiful and that they look 'hawt' even if, somewhere inside they know it to be 'ego felatio', as you put it. Support takes many forms.
