You're losing your time and energy trying to convince them, this " genetics " gospel has been Joe Weider's narrative for decades to justify his bodybuilders being natural...
And now here we go with randoms turning into muscle/performance machines in lesser technical strength sports ( namely powerlifting ) that actually requires close to no specific athletic ability but strength, and in a record time..
Didn't you notice the youth/subjunior/junior records are getting more and more ridiculous lately...? And we are talking about sports where people reach their max potential in their late 20's/early 30's..
You can be a world IPF subjunior champ in 2 or 3 years of trainnig nowadays it seems.
As far as I'm concerned , t's certainly not due to human genetics sudden leap in quality, neither can the increase of the pool of people doing power explain this, especially since those " natural but genetically gifted " lifters popping out of nowhere are suddendly gving the eastern europe and forme soviet republics competitors a run for their money ( who we all know are natties AF ) ...
Same as with the Oly Weightlifting in CF, years ago being a 265-330 olympic weightlifter was solid AF for anyone not being a national competitors and nowadays random CF boxes are full of that kind of lifters, who don't even do that much WL.. Same " secrets " suddenly spreading worldwide thanks to the internet I guess
