I mean, Obama and Trump actually said that stuff. Yes, it's misleading, but it's "true" in some kind of abstract sense.
This video of Pelosi was a straight up lie. She didn't say that stuff that way. You get that there's a moral difference here, right?
The fact that people can be fooled with cleverly structure and possibly misleading factual argument is not a license to lie like a sumbitch whenever you want. And that you seem to think so is horrifying.
