Oh, it probably does include people with disabilities, but not overtly, because decent normal people are supposed to feel sorry for the disabled, whereas gay people or drug addicts or whatever chose to be defective and are therefore unforgivable.

There are so many potential underlying assumptions about what constitutes normal or decent in that statement that it's almost impossible to guess what they all are. Who knows what religion, or politics or weight limit or education level someone needs to qualify as normal and decent.
