In his most famous book, "The Closing of the American Mind", Bloom criticized homosexual politics in American universities on an issue relating to his core concern, liberal arts education, or the "Great Books" liberal arts curriculum, making a distinction between a politically self-defined group of homosexual activists and homosexuality "per se". Although Bloom, in the wake of his literary stardom, explicitly stated, at a Harvard University gathering (published in "Giants and Dwarfs"), that he was not a conservative, he was much admired by writers in conservative publications such as William F. Buckley, Jr's "National Review".
