WASHINGTON—The American Enterprise Institute (AEI), a conservative think tank, has criticized the U.S. Supreme Court for its ruling in Free Speech Coalition et al. In a briefing published by the institute on Tuesday, nonresident senior fellow for technology policy studies Clay Calvert explains the rationale for criticism. Calvert explains that the conservative majority of the high court found a carve-out for First Amendment protections over controversial forms of expression, such as porn. "The group here is the Free Speech Coalition (FSC), which describes itself as 'the trade association of the adult entertainment industry based in the United States,'" said Prof. Calvert. He points out that nowhere on the Free Speech Coalition's website does it mention the term "pornography," which is a socially stigmatized term.
