Can you think of any government program that has ever been discontinued after congress has created it? I know I can't.
So, this rhetorical question is one that you found compelling. You saw it, and thought, "That's a killer argument. The government is out of control, and only a radical outsider like Donald Trump can save us from it".
The problem being that it's actually a total and utter lie. Ask an uninformed person - that is, almost any US citizen - that question, and a large fraction of them will start to genuinely believe that no government program has ever been discontinued. But they will be utterly wrong to believe that.
This is what propaganda is. Making a lot of people believe a lie. Why? To get Trump (re)elected.
Ask informed people, and you get a list as long as your arm of discontinued programs. The whole thing is exposed as a cruel hoax. So, how do you respond to that?
Do you try to get informed? Maybe you start actually looking for the answers to such supposedly rhetorical questions, to find out if the things they are hinting at are lies. Maybe you start to question the firmness of your own beliefs - after all, you believed this lie because it fitted with what you already wanted to be the truth.
Or do you look a bit deeper, and ask yourself, "If Donald Trump had a good reason to deserve my support, why does he tell me lies about reality, rather than telling me things that support his rule that are
true?" If there are any really good arguments, why are so many bad arguments being made, and where
are those good ones?
Maybe you should think long and hard about the possibility that all of your "reasons" for supporting Trump are untrue. Maybe he's not even a "radical outsider", but is just a lying piece of shit who has only his own wealth and status in mind, and doesn't care if he utterly destroys your life, livelihood, family and country in his pursuit of those things.
Do you have the bravery to challenge your own pre-conceptions in that way? It takes serious balls to stand up, not only against a big, powerful, propaganda campaign that tells you lie after lie, but also against your own ingrown desire to believe that you have not been duped.
Stand up for yourself. Stop believing the lies. When you next see a rhetorical question that makes you think, "That's so true! The whole system needs to be changed!", stop and check - is it true? Or are you going to make a clown of yourself by putting the question to people who are going to stop and check, and then are going to expose your gullability?
