This really is a problem. One that would be very difficult to curb. How many of us can honestly say that we haven't called someone crazy or nuts? On the other side, how PC can we become without constantly being afraid of offending someone. We would all, truly, become neurotic .Ableist language is definitely a problem. I try (and fail) to curb it in myself, but I find we're unfortunately so immune to how offensive it can be, so I forget. I've seen attempts to discuss it with others, and it's often met with the whole "geez, PC police" mindset, which doesn't solve anything.
