It's nice that there are special restrooms but it's not logical that because one person has some visible physical disability making it difficult for them to use a regular bathroom that their need somehow takes precedence over another.

Put it this way, two people in wheelchairs need a bathroom. Does one deserve it more than the other?

Obviously those who've never suffered gastrointestinal disease such as IBS or crohn's can't begin to appreciate that those people don't get a placard stating they are handicapped but they are as much as anybody.

People have been ostracized and even attacked because they used a handicapped restroom.  Don't judge looks.
