I used to be the same way and once worked for Ralph Nader's campaign but eventually came to the realization of what the real problem was at the most fundamental level. It's the fact that all governments commit violence and use coercion against their people. We use the vote to justify violating others boundaries to commit extortion, etc, without consent. It was once said that only by the consent of the governed, does government have any authority.
Since you're here on Steemit, are you aware that you are at the epicenter of the cure to this problem? The fundamental problem is centralization of power and control. Some call this a concentration of wealth into the hands of the few, but it is part of the same phenomena. Bitcoin and all other decentralized cryptocurrencies have within their code the ability to put authority out of a job. I've written extensively on my blog about what changes are coming for the better part of a year.
Decentralization is the answer to our political problems and the only real antidote to terrorism and everything else that ails us. By putting mathematics in control instead of the whims of politicians, peace will return to the world.
