What if I don't accept it?
Is it valid?
At some point we have to determine what is a minimum acceptable level of cohesiveness in though to take someone seriously.
I'm not saying anti-privacy people are in such extreme, but I don't like the 'everything a valid position in the post-modern relativist world'. The line has to be drawn somewhere, and some people might draw it further in or further out. But we all do it.
I don't know of anyone who likes sticking needles in themselves (aside from addicts, but that's another story), only those who understand the value of what's in them (I suppose that addicts would fall into that category, too.)
I distinctly remember my mom explaining why I was about to get stabbed with needles when I was four. I didn't mind.
Some people don't mind these kinds of surveillance. You might staunchly disagree but you have to accept that it's a valid position.
