Here’s a good post from that other thread, that might give pause to the eye-rolling:
Maybe some women object but have given up saying so (like, apparently, the OP of this thread). Maybe some women are used to it and don’t think much about it consciously, but the cumulative effect seeps into their consciousness somewhere and it doesn’t feel right. I don’t presume to know how all women feel about any issue. It’s not hard for me to avoid calling a mixed group “guys,” I have that much free will anyway. Some people seem stuck in “but we’ve always done it this way.”
