I'm not a linguist but in my mind there's very little wrong with the original sentence as pg said it. Compare e.g. with this one: "These apples are bad because they have been laying in the sun for two days." There is no reference to anything outside the sentence; "these" and "they" are sort of referring to each other, tying the sentence together. So to me this is the most shocking revelation: > Mr. Graham has since said the “these” referred to women who aren’t programmers. In our opinion, he didn’t say that to us. That's the equivalent of editing down the above sentence to say, "Apples are bad because they have been laying in the sun for two days.", and then start claiming that the interviewee is a schizophrenic because he's making general claims about all apples. :/
