They're in the entertainment industry. Their job is to entertain. Emotion is good for entertainment. I just was scrolling through Twitter and it was hilarious how many young people were tweeting that Tim Anderson is their new favorite player.
Emotion is cool and fun. You show a lot of it playing as a kid with nothing really at stake.
Tim Anderson doesn't get in trouble outside of work. Theres no domestic violence accusations. He's married with two kids. By all accounts he does a ton of work in the community and with kids. All in all a good human it seems. He plays the game incredibly hard. He's clearly worked very hard to improve his game. And he's living his dream each and every day. Being excited about that is normal and being excited for helping your team is normal.
I honestly would be fine with the takes if it were both sides, but pitchers yell, scream and fist pump all the time. Never once do these same people, who have a problem with Anderson, tell the pitcher it's too much when they fist pump; and no one would think it's ok or normal if a better ran to the mound and hit the pitcher with the at bat the next time hes up.
People break bones every year being HBP. It could kill you. And for what reason? Because he got a hit off you and was excited the at bat before?
Kids like bat flips and fist pumps and fun. The game needs more kids. Their entire promotion this year is "Let the Kids Play", and they got a guy being thrown out for doing exactly what they're trying to promote. Enough is enough.
