“For libertarians, any ideology advocating an increase in state power is a violent ideology. For anarcho-capitalists, even minarchism can be labeled a violent ideology. For communists, any system advocating private property is considered violent. What classifies an ideology as violent can be construed to fit the definition of those in power at the time. To protect free speech, we must make no exception for any form that could be subjectively defined as a call for violence,” writes Nathan A. Kreider.
