Do you think Arlington National Cemetery should be such a tourist attraction?

My best friend was a marine. He went to Afghanistan and got really bad ptsd. He ended up committing suicide this past month. I finally got the courage to go visit his new grave at Arlington National Cemetery. (I'm not sure how he got buried so fast because the wait time is usually a while). When I got there I was disgusted with the amount of people that were taking pictures, touring the grounds, chatting, sight seeing, picnic-ing and so on. This is a graveyard. People have given their lives to our country and their bodies rest here. I really believe that NO cemetery, no matter how big should be a tourist attraction. I was so angry that while sobbing at my friends grave, there were cl trips and families snapping photos (not of me) and chatting away. It makes me feel like my pain is less significant and my moment with him is not as special. Am I being too sensitive about this? Does anyone agree or disagree?
