I don't know, what about this:

Can't see how this is too relevant. I mean vaguely, but it's still a little off topic.
It's political humor. Is it unethical?
Yes, it is an ad-hominem attack on Hillary Clinton and implies that she is attempting to take over the world. This, despite containing no substance, and seemingly intending to be amusing, is actually meant to foster a certain mindset or a certain line of thought.
But -- so what? That may be biased, it may have an agenda. But as it expresses a POV it's not "unethical".
This would be "unethical":
--- since it proffers an outright fabrication (Byrd quit the Klan before Hillary was even born, so she couldn't have made the statement; Byrd as a "grand dragon" did not exist during her lifetime.)
But then --- this is not "political humor" either -- it's revisionist history.
Now if you want to include fake quotes that subjects never said and fake histories that never happened which make up the world of Googly Image memes, certainly those are unethical as they are outright lies. But there's nothing "humorous" about those so they don't apply here.
