When I was reading articles for news, "gender" often was used as shorthand for "female." That wasn't so much upsetting as it was counterproductive. I had to be very specific in searches in order to get news that was actually relevant to transgender people.
Intersex as a category is a touchy issue for me. I do not believe there is any noteworthy difference between intersex people and transgender people, and the gatekeeping between the two identities is weird.
I find it frustrating that anyone is of the opinion that gender equality exists anywhere. It's not even ambiguous. The only people who believe we have achieved gender equality are those who are comfortable, and do not themselves get reminded of the imbalance very often. That's like a white person in a white neighborhood saying that race relations are fine.
For what it's worth, regarding genders and gender roles, I'm sure that erasing gender would not help me. I feel like a real man, a normal guy, and I don't want my malehood invalidated by abolishment of my gender orientation. The idea is noble enough, but not practical.
Some people have a similar argument about marriage equality - they say they don't believe in marriage, so we shouldn't be fighting for it. Gender and marriage both could do with some open discussion, but I'm still a man and I still want the right to marry another person. It's not fair for any of us to impose our definitions on people who can't adhere to them.
