You've "made stuff up" about entire languages in your previous reply. I am struggling to find more ways to explain that, in English, it is acceptable to refer to unknown quantities or identities of people with "they" and "them".
"My bank denied my loan application again, I can't believe them!" - Correct - Unknown, amorphous entity, regardless if the rejection was specifically caused by a man or woman or otherwise.
"temp8964 replied to me on HN again, she's quite persistent." - Incorrect - Without knowing who you are, is it still acceptable for me to blindly assert that you must be a woman and doing otherwise is wrong?
