I think for the most part as hunters we haven't lost the focus of the sport. Some people choose to only shoot large bucks, others choose to shoot the first legal meat they see. I'm halfway in between personally. Early Bow season it's gotta be an 8 point or better, also does. Come rifle season, if It's legal I'll probably take it because I typically don't have much time to bow hunt late season.
So, for me it's not so much about "Not shooting small bucks and letting them grow" because I have no issue with shooting a small buck. I just wait for an 8 point or larger just because I'd like to shoot a bigger one.
What has become an issue to me is the TV shows and the media and commercialization of hunting. My favorite part of hunting is the family and friends I spend the season with. And very few shows focus on what I find important.
Basically, if it's legal, go for it.
