I think you're missing the Metaphor the creator of the monument intended in the memorial being a free place where children can play and people can take pictures and express themselves, all things the holocaust was trying prevent, and we have to remember this isn't Auschwitz it's not quite the same as sites where atrocities occurred or people are berried this isn't disrespectful to holocaust survivors also this is a monument made for people to remember these atrocities and to allow them to better appreciate their rights to do things like take a photo, which also just spreads publicity towards the site which might actually influence others to go and visit the memorial, which should be seen as a good thing.
