Bitarch’s idea to accompany offline libertarian preaching by handing out business cards seems to appeal to people. At least, I was sent a version of a business card that is slightly more tolerable in terms of both design and text. I hope you like it too. And of course, you can always create your own version.
You are passionately telling someone about your views, you see that the person is interested, but you realize that in five minutes they will forget half of the terms they heard, and when they try to Google them the next day, they will discover a lot of new things about vegetarianism and monarchy instead of libertarianism and panarchy… For this reason, it is always useful to carry a few simple business cards with you; that way, even after a very heavy drinking session, there is a chance that the conversation wasn’t in vain.
Bitarch and I have prepared a sample for you. Just print one page on heavy paper at any copy center; it will almost certainly come in handy. The business cards are made to be exactly the same size as a bank card, so you won’t have to guess where to keep them—after all, you keep your cards somewhere.
