The political within the plot

I noticed not many people pointed at the conservatist or puritanical references within the movie which haven't much to do with the plot at all. I'm talking about the scenes of farms and fields that come out various times while we hear music playing. Or the more explicit condemned issues like marihuana, mobile phones, etc. while other dangerous habits like drinking or smoking are seen as funny or acceptable.
I respect the safekeeping of certain traditions, and I definitely would never say the closing of an educational facility is a good thing. BUT I think the movie incorporates far too many other conservative strategies within its subtext that really spoil it for me. As a critique to government educational policies is fine. Even as a defense of old-fashioned ways of life is fine too. But one cannot claim that EVERY old way is better than the new and that moving forward is a bad thing.
And especially I didn't like it when the pitcher gets physically harassed in the bus by his team mates. This IS like the "code red" used in the military, and I have to say I do not agree with it or what it entails. This, to me, is a good example of how the movie defends the old conservative ways through a subtext within the movie that spoils the plot for me, be it based or not on a true story. The movie chooses very consciously where to stand politically, and that is a little too much to the right for me, sorry.
