I think the general consensus is that genuine emotion in whatever form doesn't bother us. It is the fakeness that alot of the show hosts portray.
Fred Eichler is a prime example of genuine emotion coming out after a kill. He gets just as excited shooting a doe or a spike as he does shooting a big moose, and makes no apolgies for it. Laughing, crying, smiling, high fiving, pats on the back are all real emotions that people show after accomplishing things not just hunting related.
Baseball players after winning the world series, football players after winning the super bowl, fighters after winning a title bout all show the same emotions and reactions listed above because it is the cullmination of a lot of hard work, dedication, preparation, and practice. Which pretty much sums up a hunting season for most people, so to expect hunters to act like they are at a funeral after a kill, no pun intended, is a little bit ridiculous.
When I get my first tradbow kill, you can bet that I will probably as my dad would call it, "act a fool!"
