There's no such thing as talk about politics without extremism. Anyone who discusses politics have it's belief system inside them, you can't change, no matter how many facts are shown, it's part of themselves - which simply won't let rational thinking make the world better.
So the only way to fix that, the ONLY way (regardless of it's applicability), is the inexistence of a government.
Could be made less stupid if at least people didn't care that much about the president and other politicians, make it a less important factor on the planet, so they would earn less and have less power. Once you have as much power as presidents have these days, you will make bad use of it, 100% of the times.
