Yes. This is the primary tactic for discrediting information. You don't just call the missing 18 minutes a conspiracy, you create a much crazier version that all of space is fake, and then call that a conspiracy theory.

You don't just claim that a well known not-so-secret society is totally not up to no good, you claim they are actually run by lizard people and then call it a conspiracy theory.

You don't cover up your secret bases and experiments at the south pole, you claim they are hiding a portal to the underworld and then call it a conspiracy theory.

You don't claim video footage of your experimental plane is fake, you call it a UFO and then call it a conspiracy theory.

You don't claim the CIA doesn't assassinate people with a poison dart gun, you call it a Heart Attack Gun and then call it a conspiracy theory.

You don't claim your scientists were not talking about dark rituals and opening portals to other dimensions, you claim they might cause a black hole and then call it a conspiracy theory.

You don't claim 5G won't be used to track people like farm animals, you initiate a global campaign against the conspiracy theorists saying it's bad for your health. (It may be that too, but it's the tracking systems they don't want people talking about.)

You don't hide that people have openly talked about depopulating the planet via a vaccine, you focus on discrediting the one guy who claimed they caused autism and then label everyone an anti-vaxer no matter their concerns over complete lack of safety and efficacy.

You don't argue against natural remedies being superior to pharmaceuticals, you highlight a scam artist who sold people bleach pills.

You don't discredit the effectiveness of essential oils in a myriad of treatments, you sell it as a "cure for Ebola" to the third world, and then try to shut the entire industry down.

You don't sell people communism, you sell them fear.
