Egalitarian is typically used when discussing equality in political, social, economic and civil issues. Can it also be used to portray equality in gender issues? E.g. an egalitarian does not discriminate on the basis of gender, or favor one gender more than the other.
This wikipedia entry provides an example of use of egalitarian towards gender.
Every now and then I have seen reputed print media referring to men who strive for female causes as egalitarian. For example note the use of egalitarian for gender equality here.
I believe it can be (and often is) used for gender equality.
If all people are equal, that includes gender, race, religion, status, etc.
