Getting back to the basics of this thread, you Roger seem to expand it into different areas to try and belittle people who for one reason or another do not wish to have their photograph taken. Why do you feel the need to call those who so wish it, to be ashamed? Why do you call them small minded? Why can't you accept that not everyone thinks like you?
Granted there are security cameras everywhere. So be it. When a person is confronted with a choice as to having that photo taken or not, Why can't you accept that that person made a choice? Some countries it is not a right to photograph whatever you want or whom ever you want. My example of the Hopi Reservation is just that. Many and that means right here on apug have in the past claimed that the reservations should and are public lands. They are not. Photographers, and this means a person carrying a camera, have visited the Hopi rez especially during their ceremonial times. Those photographers were rude, and interrupted the ceremonies to the point that in a few instances the ceremony came to a halt until the offending photographer that positioned themselves right in the middle of it as they claimed it was there right, could be ejected from the rez. Laws were enacted to halt it by banning cameras. It is not that I'm saying ban a camera. I'm saying think before you use that camera. Some shots are not going to be offensive to anyone. There are a lot og good grab shots. Then there are those that for one reason or another would upset the subject. We see it a lot today with parents of children. To say again that a person should put a bag on their head to go outside is the most asinine thing I have heard in response to this thread. To demand that you have the right no matter what will give ammunition to those who do want to ban the use of cameras. Common courtesy, smiling, being open and asking permission when you think it might cause trouble goes a long way to keeping that right you so dearly want. Is it that hard to respect another human being? Do you have to demean them by name calling just because they don't want their picture taken? As to the remarks about farting, Ben Franklin had it right in the late 1700's, read his book called, "Fart Proudly" It actually takes your stance. As to vomiting, well that is not something that is controlable. If it were to happen, then you just happened to be covered by what is an act of God, or Mother nature, take your pick. That person if they were being photographeed, and chose that moment to hurl, I would laugh until I cried to see you covered with your right to photograph it. Yeah I do equate them. It is not an assualt, it is what they say,,,,shit happens. You take pictures in a street setting, and well anything can and sometimes does happen. You sound more like a papparazi type than a street photographer.
