Most of us would not think of plastering our political party logo on our business.
True, but Bitcoin and bitcoin.org are not business. Like it or not, bitcoins have a political and economic background, you cannot really separate them.
Instead, I advice you to link your friends to apolitical sites like weusecoins.com or that Bitcoin Consultancy I saw somewhere, and maybe prevent them that if they come to this forum they will see heated political discussions. That's inevitable and should not be banned, IMHO.
