Firstly I form my own opinions by observing ACTUAL BEHAVIOUR, not just parrot whatever libertarian propaganda I have been reading last such as you have been doing.
World wide right wing and center right governments have been ADVANCING the same - hence why you have Obama agreeing with Cameron - a right wing Tory FFS.
Here in my country the VERY right wing part in power is bending over forwards to allow the US to have new spying powers - even to the point of suffering greatly themselves politically. The same in Australia. This is repeated around the world.
To argue otherwise is just ignorant.
Worldwide it is the most LEFT parties that are the most vociferously opposed to the spying the RIGHT parties are introducing.
And just because you are so ignorant as to call the democrats "left wing" or to totally and completely ignorant of what your typical left wing party stands for does not make it any different.
And if you think the "libertarian" party (which are so obviously referring to) will be a breath of fresh air you are a bigger joke than I am implying above.
The Modern Libertarian == freedom for the wealthy and their total abnegation of any social responsibility towards everyone else(i.e the people they used to make said money).
And all the above is so obvious and transparent it should not even require explaining. But then this is main problem with world today - too much wilful ignorance.
