If you’re ever visiting Arlington National Cemetery please remember that people are there burying and visiting lost loved ones. It might be part of your vacation, remember for others it’s a time and place of mourning. Please be respectful. Stop for funeral processions and place your hand on your heart.

...any cemetery
One of the most beautiful ceremonies that I've ever been to was at Arlington for my uncle's father that had his remains recovered from Vietnam. There were jets flying overhead, we had a motorcade escort all through DC area, it was beautiful.
How many people do you really think to reach who go to this cemetery?
You do know you're posting to people from Uzbekistan, Japan, Germany, France, canada, Korea, etc etc etc?
To be more productive in my comment: I would suggest you make the comment unspecific , e.g. "when visiting a cemetery...."
My comment was specific to Arlington National Cemetery which is also a popular tourist destination. Stopping and placing your hand over your heart as a civilian for a passing funeral procession is specific to that place.
