Daylia - we aren't talking about the National Anthem - and BOTH are played. This is the 7th inning stretch.

ALL major league ballparks also tell the crowds when to cheer and boo. We aren't drones.   If you go to someones house and they say grace before a meal, you sit quietly and politely if you do not practice the faith.   If you disagree with the sentiments of a song, sitting down is probably the greatest protest you can give.

Booing a country and it's citizens lowers the fans to the same level. They are no better.
