The amount of candid photography should be reduced by 90%, that's my estimate of how much of it is really 'needed'...
That's one position to consider. Actually, it's not unreasonable to suggest that 90% of numerous other activities that people engage in don't qualify as 'needed' either.
For example, here's a variation to consider:
The amount of
discussion and debate about candid photography should be reduced by 90%. That's almost certainly some people's estimate of how much of it is really 'needed'.
So you equate discussions about candid photography (or any other topic, for that matter) on Internet fora with the question of whether or not you should have a right to take another person's photo in the street?
I haven't equated anything with anything.
I haven't presented an analogy either. I presented a variation of the other poster's statement about how much of anything different people think is 'needed'.
whatever. you sought to say that the same could be said of many other things -
I contend that it's not unreasonable to apply the same thought to numerous other activities.
your purpose was to trivialise the debate (presumably because you don't think it is worth having).
People may choose to question the necessity of candid photography, and people may also choose to question the necessity of debates about it. Their
purposes for questioning these things would be a different matter.
Also, my purpose for commenting on
that idea could be another different matter. You don't know my purpose, and are just inferring it based on your perceptions.
It wasn't very illuminating.
Perhaps not, though it's at least as illuminating as the comment to which I replied.
