I dont believe the guy knew where are u from.
"Monkey" is just a basic insult here, and should be considered as a local idiocy, not more.
And what I do not tolerate, when ppl are being pussies "dont call me that, dont call me this, this is unacceptable, blahalbabla". U aint a woman (altho they can do the same), u can silently beat the sh1t outta mf here. My suggestion is to leave la2 as it is, cruel and real, unlike the sterilized workspace in big corporations (i guess this is where it all comes).
Also this kind of behaviour it is good to see who is who, it unveils the real sh1t behind the nickname and u know for sure - this guy deserves to wiped;)
Manners, honor, able to be polite, dignity in the end - is really rare stuff not only ingame:\
Just dont follow such ppl. Be better.
