It's why they tried to get rid of it

Wait, I don't think you understand the gravity of what you've just suggested: autism caused Pluto.
- No, you got it wrong. Autism exists since like forever. It's the diagnosis that caused Pluto.
  
  Doctors created Pluto as a distraction
- Look man when I was a kid Pluto was a planet. Therefore Pluto will always be a planet.
  This mental inflexibility on my part may be related to autism, but I will never admit it.
  
  Don't worry I also find myself being stubborn for no logical reason. In many areas of life.
  
  Pluto was created to be destroyed, and it's destruction would make autistic people reveal themselves plainly.
  
  Look at it this way. Pluto didn't change, we just changed the definition of a planet to exclude it from the cool kids club because if we included it we'd also have to at the very least invite Eris too, and nobody likes Eris (hence the Trojan War).

The knowledge of Pluto causes autism, clearly it is an elder God cognitihazard.

Diagnosis unclear, I haven't been diagnosed with Pluto, yet...

Shark attacks cause ice cream sales
- Are you suggesting there's a common cause for pluto and autism?
  
  No, the opposite; it's a classic example showing that correlation doesn't necessitate causation. I was just playing with the phrasing to imply the humorous inverse that there is a casual link.

Thousands of people suddenly start staring into the night sky, exhaustively cataloging everything they see, and writing long journal entries arguing over whether a vague flickering dot is a planet or not.
And you think Pluto caused Autism?
- Some guys got so obsessed with reforming and polishing glass, that they used that to see the vague flickering dots even better.
  But also, have you seen the night sky without light and sound pollution? How can someone not just stare at that every night and memorize it?
  
  Getting really far out into the woods and seeing the Milky Way in all its glory is a transformative experience, without a doubt.
  Maybe we have it backwards. Maybe the light pollution is what causes the Autism and we just got lucky with Pluto before the sky was closed up.

Pluto's original name was mRNA !!!

Are you suggesting that Pluto is inside of vaccines?!? Alert the media!!!

The thing with jokes like these and Birds Aren't Real and Russel's Teapot and stuff is just that we don't believe in them and the people that do believe in the vaccine cause autism BS is that they do fervently do.
- I don't think I understand your point.
  
  He's missing some punctuation, but the point is that the burden of proof ought to be on the people making the claim instead of as it commonly happens, that people state something wild and then spend their time arguing against the proofs against it. The secondary point is that people who do this are already blind to this, so they are basing their arguments on something that only they believe, and strongly believe without proof.
  It makes discussion futile, because the people believing in random stuff are asking for evidence against something untrue that is based on something untrue which is based on something untrue. It's 2 or more steps away from logic.
  I don't know if that made any more sense, so let's make an allegory with math.
  Let's say a person wrongly believes that 2=3. This belief is unknown for anyone besides themselves. Based on this, they conclude that 2x3=4 and state that openly. So a sane person would argue that 2x3=6. The first person then claimss that 6 is wrong, and the second person will attempt to prove it logically. It does not matter how much proof the sane person provides of the 6 because the first person does not understand that from their belief. The 2=3 belief is never discussed, only the 6.
  The result is that they will never agree.
  The best way to counter this kind of stupidity is not by logical argumentation. It's better to simply ask "why?" until the wrong person argues themselves into a position of belief, which can then be countered by a final "why?" to which they have no answer and are forced to reevaluate their belief, and hopefully come to a better one, or at least start questioning that instead.

Is that why autistic people are trying to convince everyone that Pluto isn't a planet?

when i was a kid and we weren't paying attention, a saying was "is your mind lost in Pluto?"
- Earth to Expatriadio

Smokers get cancer
Smokers carry pocket lighters
Therefore pocket lighters cause cancer

Grilled Cheese sandwiches cause Autism
Prove me wrong
- That's easy... Pluto causes it. I mean that's why we are all here.
  
  So, if I understand correctly, Pluto causes grilled cheese sandwiches?

Lies, damn lies, statistics, and Pluto not being a planet.

Post hoc ergo proper hoc.
- Speak English to me, doc! I ain't no scientist.

Pluto isn't real wake up sheeple!!!

Ahh. Post hoc ergo propter hoc. I probably can’t pronounce it, but I sure recognize it when I see it! Its has got to be one of the most sophisticated ways to display ones ignorance.
Another fun one they always seem to like to use is:
“NUH UHH!!”
(By the way, it was 1911)

Nice try, but wasn't autism 'discovered' in 1933??? Big Pluto trying to get its planet status back over here. Psh

Um, actually, autism was termed in 1980s...
- Nope. It was 1911.
  
  I did not know eugenics was named after a person. I thought it was like, a scientific sorta term.
  Oh shit, it wasn’t. Just a weird coincidence.

PLUTO IS THE BEST PLANET IN THE UNIVERSE!!!!!
- And Pluto knows that it's Hot Shit.

Finally we discover the cause of autism. We are coming for you Pluto, you wanna be planet.
- We are coming for you Pluto
  To throw it an appreciation party!!

best argument for making pluto a planet yet
