Yup. If someone who is actually disabled prefers that term, well, I'm not going to police identification. However, I hear it most often from "allies" who think that they know better.

That is AWESOME about WisCon. I have scent triggered migraines, and part of why I dropped off going to Boskone when I lived in the area there was because so many people wore perfume. It seems to be less of an issue here in the Seattle area; there are some people that wear scents but they tend to do so more lightly and they tend towards natural essential oil based perfumes like BPAL (artificial scents are where I have issues, although this doesn't make a difference for everyone; my partner is much more sensitive than I am and can't handle virtually any perfume or even strong shampoo/conditioner).

There is definitely a difference between Handicap and Access. I will generally forgive the Handicap wording IF they are otherwise making an effort rather than a token, but generally the wording is a good indicator that no, they don't really care all that much. :-\
