Then ask, what value does broadcasting her health status everywhere provide society?
Hopefully this will help inform you of the differences in these separate acts, since it seems to have blown right by you at light speed.
(Not who you replied to, but...)
I believe Chelsea Manning deserves privacy for an issue such as this, but also hope that the situation will (at least) make more people contemplate the extreme nature of solitary. I would be undone fifty times by now if I were isolated by force.
"Information that some people would have preferred to keep private" is a general statement that could be applied to anything from a teenage girl's diary to an impending nuclear attack. To handwave that away is to make the entire matter meaningless.
Did we all need to know salacious details about Muammar Gaddafi's "voluptuous" Ukrainian nurse? That seems very much the same kind of data to me.
Is that not why she's come into the public eye? For releasing private information that some people would have preferred to keep private?
This isn't a comment on whether her leak was the right thing to do or not, just the whole "Treat others like you want others to treat you".
