It doesn't make sense to ban women in SaiGAR if people are still nominating and voting for them because they think they are GAR. Banning them because "which hurts any chance for any female" just means the trolls have won.
They ARE in the vast minority because GAR is essentially a male-dominated term, and this is reflected in their obvious domination of the contest. It's harder for a woman to be GAR because it goes agains their gender. This is reflected in SaiGAR by women being in the minority.
People are still voting for Kino, Cronelia, Teresa, etc because they think they are GAR. Irregardless of how many votes they get, this is still the truth, and since what means "GAR" is defined by the community, banning characters that the community have nominated to be in SaiGAR just isn't right.
