For those who do not yet know, David Horowitz is a former leftist liberal professor who has since converted to conservatism to wage war against his former ideology. Horowitz now travels the country warning about the inherent dangers of radical leftism and radical Islam, speaking at universities and writing books, as well as operating websites to further spread his important message. As such, Horowitz often ends up in confrontational arguments with Muslim students who seek to challenge his lifetime of experience and knowledge, as we see in this older clip.
