Here is Jimmy Kimmel's quote:
We hit some new lows over the weekend with the MAGA gang desperately trying to characterize this kid who murdered Charlie Kirk as anything other than one of them and doing everything they can to score political points from it.
We hit some new lows over the weekend. Why did we hit new lows? Is it because somebody said a true thing? That wouldn't be low. It must be because somebody said an untrue thing, what is that untrue thing and who did it?
Who did it?
the MAGA gang
What did they do?
desperately trying to characterize this kid who murdered Charlie Kirk as anything other than one of them
and
doing everything they can to score political points from it.
The and means that both of their conditions must be wrong, otherwise you would us or.
If they were wrong to characterize the killer, (an adult, not a kid) who killed Charlie Kirk as anything but one of them, MAGA, then he must be MAGA.
People had a natural instinct to understand that Kimmel was saying the killer was MAGA and they were right, because that is an inescapable logical conclusion.
Added: On top of the logic, the rhetoric implies rage at the MAGA gang for denial of something really obvious. Which is kind of the reason it creates such outrage--Kimmel was vociferously and crudely denying the actual obvious reality.
