"Orville, Wilbur, what am I holding in my hand?"
"A butter knife, Ma."
"Right. Now, watch what happens when I drop it....Clang!...Did you see what happened when I dropped the butter knife, the heavier-than-air butter knife?
Did it fly? Did it go flying around the room singing, 'Fly Me To The Moon?'
No! It didn't fly because it's heavier than air. And if something is heavier than air it can't fly. Everybody knows that, everybody except you two. Couple of damn...deniers!"
And, before the Wright brothers, there was the 'denier' Copernicus who knew that it was the Earth that revolved around the sun.
And Lister showed that the almost 50% surgical mortality of the day was due to preventable infections while the surgeons kept sharpening their scalpels on their boots because they weren't going to listen to that upstart 'denier,' Lister.
And schizophrenia is caused by 'poor parenting.' (It isn't.)
And stomach ulcers are caused by 'stress.' (Uh-uh, a bacteria, H. Pylori.)
And, until 1973, homosexuality was a 'mental illness' caused by a domineering mother,
"Oh, doctor, my poor little Ru Paul. And it's all my fault."
"Yes it is, Mrs. Cohen. But cheer up. At least you'll have someone to give your old clothes to. You know what your husband's things look like by the time he's ready to get rid of them. Men!"
And now it's climate change...or is that global warming or global cooling or global drying or global wetting? Whatever...It's bad and it's our fault. All the experts agree. So don't be a damn...'denier.' Please, just shut up!!!
Well, science doesn't advance by getting the 'deniers' to 'just shut up'.
Science advances by asking questions. Questions, questions, and more questions. And it's the 'deniers' who are the ones asking the questions....and making the butter knives fly.
