The 50+ main debate topics at ProCon.org are listed below along with their respective core questions. Our topics are presented in one of two types of ProCon.org websites. A "standard" site consists of many pro/con questions and expert responses related to the debate topic and takes more than 1,500 hours for us to build. A "micro" site takes about 400 hours to build and offers the top pro and con arguments of one core question. Both types of sites also have left column research projects, historical backgrounds, readers' comments, quotes, photos, and more.
