No one would even give a crap about these photos if not for that root cause.
This is why intent is at the root of these issues. We won't likely address these issues of public domain vs privacy unless we address the root of why anyone really cares about the issues in the first place. I don't think people are saying I don't like art. I think people are saying "I'm sick of being sexually objectified"
I say all this as street photographer myself.
Also food for thought. Would this have been as big of an issue had the photographer been a woman? Would it had gotten the same push back? These are question that dig more the root cause of why this has less to do with the photo and more to do with who is taking the photo and why.
