Work Within the Green or Other Third Party?
I know less about the Green Party than the Libertarian Party. The socialism promoted by their national platform and presidential candidates has been a turn-off for me. On the other hand, I have met quite a few people within the Green Party who have ideas similar to ones on this site. Many Greens are Georgists, and so am I.
Much of what I said about the Libertarian Party could be applied to the Green Party, only replace anarcho-capitalism with socialism. The Libertarian Party calls for too little government to be viable; the Green Party currently calls for too much. If the Green Party is to do more than elect George Bush as president, then it needs to move closer to the mainstream.
The red articles on this site provide plenty of ideas for being anti-corporate without replacing big corporations with bigger government. The green articles provide some on protecting the environment while often shrinking bureaucratic red tape. (At the time I am writing this, January 2006, the green selections are still a bit sparse. I have been tied up working to reform the Libertarian Party and doing the research for the Bible-based blue articles. Rest assured, I have plenty more environmental material to post.)
Regarding Other Third Parties
As far as I can tell, the other third parties are either too small or too much like extreme wings of the major parties to be worth bothering with. Feel free to disagree. In my opinion, if none of the four parties covered so far meets the bill, it is time to start a new party, which is the subject of the next section.
