筋金入りの・・・ ― card-carrying

"card-carrying"という形容詞があります。そのまま訳すと、“カードを運んでいる～”となりますが、より正確に言うと“カードをぶら下げている～”となりましょうか。

ここで言う"card"とはIDカードのことです。


"I had this problem," he reminisces. "When I found the first differences between male and female in the brain, I got attacked by the feministic movement.

とありますが、ぶっちゃけて言うと、筋金入りのフェミニスト、とでもなりましょうか。正真正銘の、という意味もあります。

IDカードは身分証のことでもあります。元は政党員の党員証のことを指していたようで、“筋金入りの”という意味以前に、（ある団体、組織などの）正式メンバー、というニュートラルな意味で使われていたようです。

下記はどうでしょうか？


"I knew at this moment as well as I could ever know that these guys sitting five feet behind me were card-carrying members of the mob.

"So how do you drive when you know that the fellow sitting just behind you puts bullets through people's brains for a living? Carefully!"
