How many other places in the world could she have taken this photo? All of them.
As a start, 6 million Jews were exterminated in camps like this, as well as many, many others, including some of my relatives.
I have my views, and they aren't shared by everyone. I am obligated at times to go to a church, and as an atheist, I keep my mouth shut and let people observe their sacred places.
This location is sacred, to many people for many reasons. Nothing about it suggests "Look at me aren't I cute?".
The events that happened there represent some of the worst that man can do to thier fellow man. The defeat of that ideology and liberation of these camps represent the best that man has to offer.
Men women and children died there on mass because of who they were. Men died on mass to free, protect, and avenge those people.
When you are walking on someone's grave, please show respect. When you are walking on a peoples grave, yes, take a photo, commemorate your experience, and have the humility and humanity to do it in a way that honors those who died.
I was not going go let my beliefs prevent me from going to my fathers funeral or nephews wedding.
I have never been shy about expressing my beliefs, and haven't been compelled to a Sunday service since I was in basic training in the 90s.
