He simply neiled it

Challenge it with what?
Bullshit? Yeah, I can see how they might find that tiresome after awhile.
What else ya got?

Or conflicting findings.
My paleontology professor led a team of graduate students to develop a new theory about dinosaur skeletons that disproved and replaced an existing one. When presenting the theory at a conference, nearly everyone there happily accepted the new findings.
Guess who was the one scientist that didn't?
The guy whose theory just got one-upped.
Coincidence?

That's not a challenge, that's when disproving something. Of course the guy that came up with the previously accepted thing is going to be upset. Even if he wasn't visibly upset, he'd probably be disappointed since he worked so hard on his own theory.
Guest made it sound like the entire community would come after you with torches and pitchforks for daring to engage in science.

This dude is a douche tho. If science had to do a study and prove previous science wrong he'd deny it, i bet ya my big dick

If the new science had evidence to support it, he would debate it and try to find any flaws. That's how science works
