I really don't see the problem with it unless you're specifically referring to women as female but never refer to men as male.
Not everyone is a native English speaker either and even amongst native English speakers I really don't think there's some alterior motive behind people doing it.
I think it's VERY obvious when someone is doing it in a derogatory way and I don't think that the OP is.
The OP also refer to himself as male irl.
I just don't think this is something average people ever think about it's mainly something that becomes seen as problematic online because people read too much into things ( and granted some shitty people do it, but like I said it's very clear when they're doing it to be derogatory ).
In a lot of languages the two are also the same word so people will treat '' male '' and '' man '' the same in English too I really don't think it's that deep 99% of the time.
Like I mentioned above the OP refered to himself as '' male '' too.
I am not sure what you mean with '' like that ''.
I really think people are over-thinking this a lot, it's not only men referring to women as '' female '' either this is just how normal people speak who don't essentially live on the internet lol.
I think if someone is very clearly being derogatory about it then it's fair to point it out, but in this case it seems like people are reading way too much into the OP and their intent it's a bit silly.
Edit: I realize the OP is playing on a NA server, but that doesn't mean they're a native English speaker either nor that they're from the US.
And either way I really don't think most Americans ever think about this.
I try to avoid it with both men and women but it's something I actually have to actively think about and in all honesty I feel kinda stupid for overthinking it a lot of the time and it feels silly to me.
Literally the only reason I do it is to avoid arguments like these and people assuming I am a bad person because I said a perfectly normal word.
It's dumb.
