Tbh I'm not in that habit either, I had wrote "he" but after I posted I caught the :3 in her uname, so I checked and came back and corrected it. Also, I had a feeling from the writing style she may have been ESL which I was going to mention too if so, but yeah both those reasons are why I checked this time.

As to the rest of it, she's already corrected you that she did not edit the "females" out so I don't have to mention it. Instead I'll mention that A) You had no knowledge of her will to speak better before you were rude to her about her word choice, so you can't claim you were "just trying to help bro" or anything like that, B) if you were trying to "help her speak better" being a dick about it isn't the best way to go. Hell even if you're trying to police a woman on how she speaks about women because you think how she does it is immoral, being nice is a much more effective strategy, "catch more flies with honey" as it were (but for fruit flies use vinegar.)
