You're not (not "your") the arbiter of what's polite. You're not (not "your" again) special for using your (not "you're") real name nor for being a season-ticket holder. You're (seeing a pattern yet?) just a guy who thinks too much of himself.
Also, Ems (not EMS) is short for Emeralds, who've been drawing fans of all kinds for all kinds of reasons for decades. My kids liked the ice cream served in batting helmets the best. The Bebans did a great job back in the day.
Bethel Park? Heard of it but wasn't around here back then. Still doesn't make me any less qualified to comment than you. Try getting used to that.
