The ignorance on this thread makes me cringe so hard. I understand if you aren't educated about gender studies, but at least show some respect to other people's choices to be agender, or any other gender that they indentifying themselves as. Just because you're uncomfortable about the idea of people who don't fall into the gender binary (male and female) doesn't mean that you should make fun of them/troll or the idea of their equality. Don't say that it doesn't exist, or intersex people don't exist, because they do, even if it's a minority. And just because you're a minority doesn't mean you should be ignored.

You definitely do NOT need to go under the knife to be trans. You can full on identify as a man if you still look like a woman, because you think you have more masculine personality traits.

Gender=Based on the mind (your choice)
Sex=Based on your genitilia (not your choice)

The jokes about identifying as a helicopter etc are not appropriate at all, because it shows that you aren't taking this seriously. Why should it be taken seriously? Because this affects people in the minority, who are more susceptible to violence based on their gender (or lack of) to feel as if they aren't accepted. It also affirms people that it's okay to bully or make fun of people who choose a third gender, which can lead to gender based violence.
