Truism: It’s OK to sing the National Anthem at any place, any time, in the United States.
This truism is not true.
There are always exceptions. Sometimes it’s inappropriate to sing period. Please do not ever sit behind me and sing in a movie theater. You may end up wearing a box of popcorn.
Besides that – if you thought, like me, that your freedom to express patriotism is unlimited in our country, you would be wrong.
You cannot sing the National Anthem at the Lincoln Memorial in Washington, D.C.
