Here's a site containing a collection of unforgettable photos that literally "changed the world". These days, most sites feel the need to let anyone and everyone "comment" on their contents. This often invites "trolls" and other anonymous troublemakers to write sarcastic remarks that sometimes deviate from the intended dignity of an otherwise serious effort. Sadly, this site (the photo site) is no exception.
So whatever you do, do not read the first two comments about the "5 year old Mother", the "Anne Frank" knock-knock joke, "Child Draws Home", and just about every other comment on the site.
