Even in May, emotions were running high.

In general, apart from limiting sales of booze, at some point MLB teams — as well as teams in other professional and college sports — may have to consider a dress code of sorts: That is, banning fans from wearing team jerseys into a stadium for security reasons, even if both mean a loss in revenue.

Attending a game while wearing a shirt with some other dude’s name on the back does not mean that you are on the team or that it requires you to uphold the “honor” of the team when someone is talking smack.

Further note to fans: Players don’t care about you.

Why do grown men and women wear team jerseys anyway? Possible exceptions: employees of the team, stockholders in the team, or immediate family members of players.
