That's the subtle difference?
Suffice to say that it's a surprise for me.
I had an epiphany, could it be "Stop making idiot's comments" or something?
It must be that way. I mean, "idiotic" is an adjective and "idiot" is a
noun.
We use these for well-known things, some can be hyphenated and some are
written as one word.

Yes, that's it, more or less.
"...idiot comments" are comments made by idiots.
"...idiotic comments" are comments that could be made by anyone, idiot or
genius, that happen to be idiotic.
