Like Dougly says, most camps mix it up based around a theme or more general identity ("queer camp" instead of Q/POC camp or Queer Jews or Queer Leather Camp). Comfort & Joy is one of the largest of the queer camps, and is a definite mix of people. At this point I don't know if they're still accepting members.
There's also a Queer Burners page
on facebook you could try, as well as a Queer Burners webpage
(you have to register to enter, I honestly don't care enough to register so I don't know if it'll be useful for you).
