You need to not be so quick to jump down people's throats, Jeimi. Try to calm down, please.
It is a valid issue, for sure, but this particular instance (LovelyAngel's photos) is not all that applicable. It seems, by looking at LovelyAngel's photos, that LA is the kind of photographer to discern the difference between an intrusive and non-intrusive photo opportunity. The photos shared are positive and present each subject in a very beautiful light. I'm not pretending people can't get upset by unprompted photos, but I think this particular instance is not indicative of the problem you pointed out.
Perhaps it'd be best to start a new thread if you would like to debate the issue further. Let's just try to keep this thread focused on sharing photo collections, yeah? ^_^
