If all of my photos were of buildings, pets or landscapes, I’d have no problems. But, often enough, I photograph people. Not paid models. Regular people.
Creative Commons is sensitive to the issues of commercialisation, but appears to be agnostic about causes, politics, religions and ridicule — I’m not.
I'm familiar with my rights as a photographer. I’m familiar with the rights of others regarding “fair use.” I’m familiar with the laws regarding photography in public places. And, I’ve read the views of some who see CC licensing as a useful tool in the promotion of their work and their art.
It’s not for me to dictate to others (it's bad enough that I preach), so I will put this in personal terms: It doesn't appear to me that any of the CC Licenses afford me the control that’s consistent with what I regard as my responsibility.
Creative Commons provides great solutions for many kinds of works, just not mine.
