Radical inclusion means that everyone is welcome.
We had a HUGE discussion about radical inclusion in the Israeli community. Partially because people were asking what would happen if we have massive amounts of "Arsim" coming in. It is not an easy discussion.
Would you radically include a Nazi? Somebody who ideologically wishes for your death?
Fact is, a burn is an amazing place to let people from all classes, races, ideologies meet in a politically neutral area. I was the only arab between 3000 jewish burners and I felt that I did have a huge impact on the people I met.
On the other side, people who do not respect the rest of the 10 principles are not welcome. In the case of the rich camps they lack participation and de-commodification. Putting up a gated community is against the 10 principles. Participation goes both way. You participate in other things and let others participate in whatever you are doing. Its not about radical inclusion in the end.
I don't think that the principles should be changed. Keeping them the way they are now lets people discuss them and actually think about them, which might even transfer into their day to day life.
