Tristan, you were insensitive and impolite when you said boyracer1981 should be more specific than just saying he was disabled, and stating that he's probably got something between an ingrowing toenail, or no legs at all. So you were wrong as well as his disability is not in the range you suggested.
I don't think it's reasonable to expect everyone who is disabled, to express their disabilities in every case, and not simply say they are disabled. In some cases they may be sensitive about that themselves. You could use your imagination. Consider that someone who says they are disabled, might have gone through a hard time, and doesn't deserve to be patronised by you. If you want to know someone's disabilities, you could ask, and they may or may not wish to reply.
This is nothing to do with what you or boyracer1981 are discussing, I am talking specifically about that post you made, it was rude, it's not just "you", it's not just "lack of political correctness", that post was just plain rude. Got it?
