I really wonder about people who can't do a simple two second search...
Google
Ok, so there are two sides... There is ALWAYS two sides. When you see someone standing over a dead person, with a smoking gun in his hand, and he says he didn't kill that person, do you automatically assume that person is innocent? So why do you automatically believe it when WHO says they are innocent?
One side, which seems to have absolutely not reason to lie, and seems to be acting in the best interest of the people, says that WHO is sterilizing women, and even gives details about how it is done.
The other side, has access to billions of dollars and lots and lots of people who keep complaining that the world is over populated, many of those people ready and willing to sterilize people. Lots and lots of people promoting sterilization all over the World. Very likely has full control of the press, and is able to force cover up stories at will.
I'm not saying you have to automatically believe in the first side, but you really should be demanding a proper and trustworthy examination, not by some government official, which nobody in their right mind trusts, but rather by thousands of local, close friend, chemists, all over the world.
