I agree with the above points. I do want to point out that for every 1 giant you see with a kid behind it, there is likely 100 others who shot the smaller ones but just did not display the photo/send it in. It's the nature of the news outlet you are seeing. I do think maybe it is trending upward though (which is the whole issue), but just wanted to point out that lots are still on our train of thinking (all of the above posts). We just don't always see it on social media.
Good point. Little Billy with a button buck gets shared on FB and friends and fam give him a pat on the back but not many people see/care. If little Johnny's dad gets his self worth from social media glory (or worse - income and endorsements) for killing big things you best believe little Johnny's bruiser is going to get as many views as his dad can get it and it'll be shared far and wide.
For the casual hunter majority, i imagine most parents just like getting their kids out there. Sit in the same stands they sit in for reg seasons regardless of wind, access, etc, and are happy to shoot whatever shows up.
