Would you suggest a word meaning "one who advocates equal opportunity"?

I should say libertarian just for the smiles... but how about....

Self-determinist.

or "Rights advocate"...

Not bad, I am looking for a single word...if you have one to extend, I will be in your debt. I have had doubts about "egalitarian" since Ruth Bader Ginsberg laid claim to the term.
