I fail to comprehend what you feel justifies such name calling and attacks - let alone the assumptions you are making about others who you don't even know. Please explain to us the source of your anger - we'd all like to be able to understand.
I can only speak for myself, but I do not photograph "dwarf people" as you refer to them - or anyone else who is disabled without their permission and knowledge before the fact. Doing so would be exploitative - and just the thought of using a camera to exploit the disabled makes my skin crawl.
Obviously not all photographers feel this way. As for me, I have more respect for my subjects, the art of street photography and for myself than to crawl in the gutter by exploiting disabled persons with my camera. There are too many others who are willing to take that low road. They can take it without my company.
No one (other than you, that is) said anything about "photographing at length" any family or their activities. One of the articles of faith in street photography is that you photograph in a candid and unnoticed manner that does not interfere with or influence the actions or reactions of your subjects. This means that you make perhaps three to six images of your subject and then move on, having never disturbed them or having been noticed to begin with.
This is the way the founder of the genre - Henri Cartier-Bresson - photographed. It is how I endeavor to photograph on the street. HCB is my role model, not the paparazzi of TMZ or any of the stalkers who photograph for the low brow gossip rags on the magazine racks at every convenience mart and grocery store.
Apologies, but this statement just doesn not hold water. Here in the U.S., the courts have already ruled that freedom of the press and Article One of the Bill of Rights applies to ALL photographers, not just those who are employed by news gathering agncies or those who possess " legitimate media credentials."Having a camera does not exactly give you thugs the right to pursue, having a legitimate media credential might
Regarding libel law - libel is defined as "when an image is used to falsely portray someone without their consent." Consent (a signed model release) is not lawfully required for images used for editorial or documentary purposes - and street photography qualifies as documentary purposes.
Hopefully this thread can continue on in a more civil and respectful manner - I did not come here to engage in name calling and verbal combat with others - it serves no constructive purpose. I came here to try to learn about photography and to hopefully pass on a bit of what I have learned over the years.
As Charles Farmer puts it, "We're all in this together."
