That guy who fear mongers in every comment section of someone squatting or deadlifting, saying that "you're gonna end up like Ronnie Coleman".
They think that spinal flexion == bad, because humans are

They probably heard it from some stooge influencer or
personal trainer; neither they nor he know what they're talking about.
Probably can't even pick up 225 lbs
from the ground.
