No worries, you did nothing to upset me :)
But you are right, there is a clear difference between being un-filtered & being a donkey, the latter usually winds up being a subject of derision(& trolling if the person overeacts to said derision in humorous fasion)

I remembered, "būtt of the joke" is someone who is treated as a joke.
