Remember on 80's sitcoms, there was a popular theme for having one of the main characters fall in love for someone, only to find out that their love interest was actually IN A WHEELCHAIR? During that time, technology enabled people to connect, without having to see the person (phone dating?). So there was always someone, like Zack Morris, who thought he'd be finding a bodacious babe on the other end of the line, only to find her unable to move her legs. This caused an emotional dilemma for our protagonist, but he/she always let the inner beauty of the object of his/her affection shine through. Then they were never seen nor heard from again.
Nowadays we don't have that because of the internet. I guess you could Skype and not know the other person can't stand up, but I think that somehow you'd just know. I think in the 70s it used to be interracial dating, and in the 90s maybe that person was really a dude or a lady. I don't know. But I do know for 10 glorious years we learned through our favorite sitcom character that people in wheelchairs are people too.
