HEY GUESS WHAT
I didn't get to finish my post earlier because the bell rang for the start of school, but here I go again now, hopefully before the next bell.
Like I said- normal = no value
The ONLY REASON we should have to call someone's mental state "disorderly" is when it causes a problem for the general community. For instance: insanity. In THEIR minds, they may think that say, raping a giraffe is perfectly normal. However, they may have to go to great lengths and hurt a number of people to gain access to said giraffes. (I dont know why, just bear with me) IN this case, then yes, they should be altered in some way.
As for disorders like ADHD, (and his opinion is actually easier for me to type out now that I have seen arlen's post) they cannot really be called disorders, just differences really. It's like, "My car is faster than yours Jim". "Well, that's not normal, let's fix that." No. We don't talk about it that way now do we? We say, "Is it a problem for you? Let's tune it to your needs." So really we are altering, not curing. And thusly, it is a difference, no a disorder.
