Alrighty then, I think we need a little History lesson

.
There were many ancient Warrior Women, mostly Pagan back in the day. The notion that women should not be warriors is largely a product of what I call Third Wave Paganism and Monotheism, when Goddess worship was stomped under the heel of Patriarchy.
Yes, there were real Amazons, not exactly like the ones described in Greek Mythology, but real nonetheless. From the Women Warriors who rode with the Mongol Hordes, to the Women Warriors of ancient Germanic Tribes, the archaeological evidence abounds with skeletons of Women buried with their Weapons.
And who could forget such Warrior Women as Queen Boadicea who led an uprising of Celtic tribes against the Romans in ancient Britain.
Then there's Queen Artemisia, Queen of Herodotus' homeland who led a phalanx against the Greeks in Xerxe's multi-national invading force.
How about Queen Samsi of Arabia, who led an armed rebellion against Assyrian King Tiglath Pileser III?
The Women of ancient Crete fought alongside the men to stave off attempted invasions.
And even within the last 2,000 years, we find such Women Warriors as Joan of Arc.
So, grab your reading glasses

, and please, do a little research before implying that Tolkien didn't write about Warrior Women (excepting Eowyn) because there weren't very many. The fact that Tolkien at least included Eowyn as a Warrior, and Galadriel in a Leadership role, demonstrates that despite the Quest being largely a "boy's club", he recognized that many Women held considerable Power at one time, before being reduced to chattel in a most cultures for a couple thousand years.
Okay, Tirade over
