Hate speech issues with Facebook
Brian Cuban has been concerned about hate speech on Facebook. While commenting "As long as there [sic] are people, there will be hate speech. It’s the human condition," he has discussed hate speech issues in the cyber-bullying and Holocaust denial areas with Facebook management. He concludes "At least in the brick and mortar world I can pull up The Constitution and Supreme Court opinions that guide me. That standard does not represent the beliefs of all Facebook users across the world but for better or worse that is the standard Facebook uses. It’s transparent. Emulate that aspect as well." He has been trying to have the pages with names such as "Holocaust: A Series of Lies" and "Holocaust is a Holohoax" removed from Facebook since 2008.

He is the Executive Director of the Mark Cuban Foundation which directly supports the Fallen Patriot Fund.
