I have a basic education, but have always been interested and in favour of free and open discussion of ideas. My main topic of interest is economic and political freedoms, but to a point - the discussion must be coherent. I will end the discussion as soon as it becomes racist, threatening (e.g.: "I identify as an AK47...), or when Godwin's Law kicks in.
I also appreciate a good discussion of religion and religious thought, although I'm rather a bit of an agnostic.
