OP's link is dead. Shame.
Anyway, onwards to the second link. The longer one differentiates themselves from another group of human beings, the longer one admits to themselves that they are not human, as they must then define why their existence of being is somehow different from another human's existence, both of which, as far as any one person can perceive, are exactly the same (we eat, we sleep, we think,) and would naturally follow that the one who separates themselves must first assume they are THE humans, or, as we can see from the many existences of various hate groups in the face of one group of sentient being, that being humans, that, in the same way all religion cannot be right, all hate groups cannot be THE humans, for which it assumes that the minority who has chosen to separate themselves from the rest of humanity must be the chosen majority, either through God's fabled word or misinformed/biased reasoning. This is how the idea of race began: one group of people said "Well our people can't mate with those people because it would never work! A white and a black cannot mate, just as a cow and a chicken cannot!" Which made sense, until it happened, and it was shown that a person of race X could mate with a person of race y, and thus, it was proven that there was no such thing as race among humans, for there was only one race: the human race. The difference is, these people had an excuse: they had no idea what would happen when a white and a black mated, or whoever it was of whichever nations. We've come a long way since then, and yet racism is still here. It's incredible.
So relating this to feminism and masculism: the differences between men and women are so negligible when you compare their similarities (we eat, we sleep, we think, we're made of carbon, and a lot of water, we like oxygen, we grow hair and nails and we have most of the same body parts and we like to be entertained and we don't usually like pain and we like to be social, at least a little bit and sometimes a lot, and we also need minor exercise to stay healthy because we like to be healthy ad infinitam) that it's a wonder such self-segregation still exists. If we've learned anything from Jungian typology, it's that people are going to be people, despite their genders. If your biggest beef with the opposite gender is "Well, they're all always acting this way or that way", then you're simply hanging around the wrong people, and when you hang around several people who are of the same personalities, then of course you'll adopt a negative attitude against all members of that perceived group of people, whether it's blacks, men, Jews, women, kids, Asians, and grandmas: time and time again we prove that a person cannot be born to hold truths to stereotypes, except for the fact that the tiny person coming out of that woman is probably not a Martian. But if your biggest beef with the opposite gender is "Well, I don't like that they have a penis/vagina and testicles/ovaries", then tough titty. Get over yourself: nobody is so important that they should obliterate a made-up sub-category of human kind so they won't be inconvenienced in their own lives. Feminism is born from a hatred of the idea that men should be the dominant sex, which they are trained to be in many cultures, including America. But counter-productivity can easily be defined as women considering women and men as two separate groups of humanity, to the extent that each sex is a different race of being (e.g., akin to a dog, or a rabbit, but surely not human), and then wishing to be the dominant sex. You don't wage war to acquire peace. You don't pursue equality by drawing a line.
Which leaves the question: "How, then, if this is true, are there still people who believe men are this way, and that women are that way?" And the answer is simple: we're cultured, from birth onward, to be different, from the way we style our hair to the very clothes we wear. Boys are expected to be this way, and girls are expected to be that way. Boys don't cry, girls don't pick their nose: that's what we're told. But boys cry, and girls pick their noses, so why continue to tell them they're different? And yet we do it: boys do this and don't do that, and girls are supposed to do this but never that, and they teach their children how boys and girls are supposed to be, on and on and on. But the point I want to make is as I've said: You don't pursue equality by drawing a line.
