How can I make a website censor resistant?

I am the founder of OpenDomain - a non-profit project I have run for 20 years that has contributed domains worth millions to charities and non profits to support open source. I have given domains to Google, OsCon, Fosdem, Jabber, Brenden Eich, Drupal, and the W3c.

One of the domains I have is http://fascist.com/ - I want someone to use it to support anti-fascist movement.

The problem is that this site may criticize some of the most powerful people in the world.

How do I set it up to be censor resistant? How do I vet people to help? How do I protect users to allow open dialogue?
