"Home of the Chiefs" at the Royals game

It's Opening Day for the Kansas City Royals who look to defend their American League title (that's still the weirdest true sentence ever).

The Royals are playing here at home in Kauffman Stadium and after the National Anthem I saw a few of these tweets....

"home of the chiefs" guy just made a cameo on opening day, during the anthem at Kauffman stadium. #goaway. .

Please stop saying 'Home of the Chiefs', you idiots.

The #Royals won the AL pennant. If you said home of the #Chiefs during the anthem, go home and never come again.

Even after a World Series appearance we still say "chiefs" at the end of the anthem at the K? Come on...

Gotta be a little upsetting to #Royals players still hearing "Home of the Chiefs" during anthem. C'mon KC fans, we should be better.

I like home of the CHIEFS at Arrowhead but it's silly to do it everywhere.

...and they're right. Chiefs fans shouldn't be saying "Home of the Chiefs" at Royals games. I'm not talking about when fans do this at Arrowhead. I'm talking about when they do it other places, including the Kansas, Missouri and Kansas State games. I don't think Chiefs fans should do this any place other than Arrowhead (probably with a few exceptions I can't think of right now).

I know for a fact there are plenty of people who will disagree with this. What do you think?
