I'm with you all on this. The worst is professional sporting events where they think they need to get celebrities that absolutely butcher it, sometimes I think on purpose. A couple that comes to mind is Steven Tyler and Christina Aguilera who couldn't even get the words right let alone sing it the way its supposed to be sung. Sometimes I wonder if most of the audience really cares or even knows the difference. My guess is they don't, and if they did we wouldn't be seeing and hearing people butcher the National Anthem.
Go to a sporting event and look around at the crowd. You see people with there hats not removed, not facing the flag, or not holding there headdress or hand over their heart. It almost seems like the National Anthem is a disruption to them, keeping them from moving on to drinking beer and eating hot dogs. Hey what can we expect when we voted for a commander-in-chief whose whole career has been a sneer at American exceptionalism, and greets everyone with a fist bump.
