@medium-density,
Have you considered the fact that there are many people who support equality and have even championed rights for women who think that this pronoun thing is silly?
There are important issues. There is ending violence against women. There is addressing pay equality and making equal opportunities for women in the top levels of business and politics.
Trying to change the way that the English language is commonly used, and has been used for centuries is, in my opinion, a ridiculous waste of time. I really hate the use of the plural which sacrifices grammatical correctness in the name of political correctness.
Of course everyone is entitled to his own opinion.
