"Moron" is not a medical or legal term. I
As far as I know, that's correct nowadays, however the word was originally coined as a medical term.
The exact word which was used in Polish is debil
which, like idiot
used to have a specific medical usage however does not today.
Can we stay on the subject of free speech instead of getting personal?
What I've said all along, however there are people here who have a hard time with that, as we can see in this thread. It says more about them than anything else.
