If you don´t have a problem with seing that we live in a sexist society,and you want to change it,why pick on words?

As I said, for precisely the same reason you are. You also are unwilling to accept that I fully support gender equality but object to the term "feminism" or "feminist". It's a gendered term. Why can't you agree to abandon it in favor of a gender-neutral term? Surely the concept of gender equality is gender neutral. Why are you fighting over a word?

This matters to me for precisely the same reason it matters to you. You are defending a gendered term that you want to use in a gender neutral way. I'd prefer a gender neutral term. Surely you'd understand a woman who didn't want to be called a "fireman" and preferred "fire fighter", despite the fact that the definition of "fireman" is not gendered. I fully support gender equality but don't like using a gendered term for gender equality.
