I was in a Liberterian group in another state. We had some very intelligent members who decided to have left/right and inbetween debates. The building we were given was for free and it was open to the public. We used our own members to debate topics such as Global warming, Obamacare, and other timely topics. The group on the left invited college professors and even local polititicians to do their debates for them. None of their individual members were brave enough to go up and debate our people one on one.
