Well, I have dated a blind guy. When I was in high school, I halfway dated a guy who had lost one of his legs. He had a prosthetic, but being in the middle of puberty meant having to be stuck in a wheelchair every time it needed adjusted. That didn't last too long though, as we had been friends for too long so it was just wierd so we went back to the friend zone.
Eta. There a nothing PC about my answer. I have lived and worked with people who were severely disabled, and needed a lot of care. It is not fair at all to compare that to the disabilities you refer to in your post, then accuse us of being "PC" because we do not discriminate based solely on physical ability. For what it's worth, the ONLY "crutch" the blind guy needed was someone to drive him around... Other than that, he got along very well on his own. He lived on his own, made his own money, cooked for himself, and anything else a seeing guy would do.
You can have your own feelings on the matter, and I won't judge you for that... But don't think that we are being PC just because you don't seem to think that there are people out there who are able to overlook what society seems to think are flaws.
Everybody deserves a chance at love.
Eta2- discrimination is not a dirty word... Yes, I DO discriminate based on personal characteristics, compatibility, and even convenience (when choosing grocery stores... Lol.) everyone discriminates based in what they need in their life, and for me, physical ability isn't a huge consideration.
