Bottom line for me on Rush Limbaugh. I disagreed some with his political positions all along, and strongly disagreed with his later alignment with Trump.
I found some of his satire inappropriate, not because he punched the wrong direction, but because it was based on false premises.
While I think he was wrong much of the time, even very wrong at times, I don't think he was evil or despicable. Backing Trump's campaign to reverse the election approached despicableness, but the man was dying of cancer ...
I think his critics got some things wrong, such as taking sarcastic humor literally and (in some cases deliberately) missing the point of "dittoes."
