Ben Carson: Transgender People Are 'The Height Of Absurdity' | ThinkProgress

You know, we look at this whole transgender thing. I got to tell you: For thousands of years, mankind has known what a man is and what a woman is. And now, all of a sudden we don’t know anymore. Now, is that the height of absurdity? Because today you feel like a woman, even though everything about you genetically says that you’re a man or vice versa?
Wouldn’t that be the same as if you woke up tomorrow morning after seeing a movie about Afghanistan or reading some books and said, “You know what? I’m Afghanistan [sic]. I know I don’t look that way. My ancestors came from Sweden, or something, I don’t know. But I really am. And if you say I’m not, you’re a racist.” This is how absurd we have become!

It is silly for us to engage in something that we have known for thousands of years. We have known what a man is and what a woman is for thousands of years. All of a sudden, we don’t know anymore. I said that is absurd. […] There are biological markers that tell us whether we are a male or a female, and just because you wake up one day and you say, ‘I think I’m the other one,’ that doesn’t change it. Just — a leopard can’t change its spots.

性同一性障害？ーーー男は男、女は女、何千年ものあいだそういうことになっているんだ、性同一性障害なんてもん、おかしいだろう、と。


偏見に対するいろいろな権利強化の活動がアメリカにあることはたしかですけど、その裏にも猛烈な偏見が未だに社会に染み付いている、というのも事実なのであります。


因みに、

Carson isn’t wrong that biology is a factor, but he is wrong that it disproves transgender identities. Indeed, it does the very opposite. Researchers at Boston University reviewed the available research and found significant evidence that there is a biological basis for being transgender. Studies have identified differences in sexual development, brain structure, and hormone genetics unique to transgender identity.

性同一性障害の場合、例えば、生物的には男で、気持ちは女、というわけではなく、生物的にも、男子の典型とは微妙に異なるようであります。
