Personally thought the bat flip was awesome, and perfect. Batista just hit the biggest homer of his career, he didn't Jack the Rangers bench the finger and run naked around base. You hit one of the biggest homers in Jay's history, emotion will run wiiiild. In the words of joe Thornton "I would have whipped my c**k out."
Sports are purely entertainment. We need more of it! I don't think Batista flipped his bat for negative feelings towards the pitcher, but for his and his teammates feelings of absolute joy. People need to see the positive here instead of the negative.
My two cents
