“You” is a personal pronoun.
“Are” is an intransitive verb that can indicate a state of being. (The weather is cold.)
“obnoxious” is a predicate nominative which renames, identifies, or defines the subject of the sentence. (You)
So when you link the disparaging word (obnoxious) to the personal pronoun, you have made a personal attack. And that is against posting rules.
I think that's a "yes" or "no" question. :)
I mean, if they're not obnoxious, then I'll take it back.
I think all the evidence is to the contrary. :)
"Typical trumpster...limited intelligence..."
That is an unverified opinion, with much evidence to the contrary.
Pretty much a personal attack.
I wouldn't fault him if he had called me "obnoxious". That's a pretty obvious truism.
