Linux is more secure than Windows !?

Top reasons that shows Linux is more secure than Windows !?

Linux is not under the control of NSA.
The NSA (National Security Agency, USA) and Microsoft recognized that two sets of secret keyswhere shipped with Windows in order to alloweither Microsoft and NSA to enter any Windows running computer in the world.

Do we accept a foreign security agency to control our bank accounts, our official mails, e­mails, our justice records ?

Do we accept our armies to run such software ?

Linux is open­source. Anybody can check if there is such a back­door in it. NSA is working on a certificated secure version of the Linux kernel for USA use, because they know Windows is not secure. If USA chooses Linux for security, why not Europe ?
