Very true. Democracy can easily turn into mass tyranny, if the people have small perspectives and consequently do not care about their fellow human. And those controlling the information that controls the masses become the tyrants. In a capitalist democracy, money rules. Money is power. So we have a construct of rule in which power is ruling with the mindless aim of achieving more power. It creates a free-fall effect, but there is eventually a landing. Here's to putting a black hole on the ground so we emerge something different, LOL.

You’re completely right that democracy does not equal freedom, since if this was true the likes of Adolf Hitler and George Bush would never have been elected. In fact most of leaders since the Civil War wouldn’t have been elected in America (or any other country in the world). As the fact is that the future is nearly always one of less freedom since (if anything) there are usually more laws left at government disposal, or new technology government can abuse.

However just because democracy sometimes oppresses the other 49%, this doesn’t prevent it being an important source of freedom.
The idea is that the other 49% will remain discontent until either their arguments improve, or they make enough political noises until a better compromise is reached (and therefore the 49% minority become more like 30%).

Sadly the way so few people own our Western mass media, and the way they will change their media’s biased positions to suit the needs of their investors demands has destroyed much of this potent democracy mechanism.
As today democracy relies less than ever on good arguments, and more than ever on arguments-issues that simply get heard-covered.

The only political acts that truly (and immediately) equal freedom are bills of rights, or constitutions. And of course these things rarely change at all (accept from when new loop holes are continuously found to be “justified” by either the courts, (or notably since 9/11 those in power).
