I see your point. But I still don't think you post came across well. His opinions weren't entirely "stupid" and should not be easily dismissed as such. And his age is not particularly relevant to whether his opinion has validity or not. But again, I understand that you were not trying to disparage his opinion based on age.
As for Jalen, he was not a "kid" or a "child" but an adult when he held his stated opinions. I understand how Beckmann might find an adult (even a young adult) holding Jalen's prior opinions to be troubling and not desirable.
