So ive played alot of dota games with my friends. We are mix up malay and chinese player, and Im a malay myself. Whenever we are together we always use Bahasa Malaysia to chat and almost always there will be one or two player start calling names like Melayu Noob malaU babi (till now dont know why they think babi is an insulting words to us  ffs its just an animal that we cant eat haha) and etc..
We usually ignore them..if we are hosting we will kick that player first (usually they start calling names after the countdown starts..heh)

The thing here, I just wondering why is this happening in a peaceful country like Malaysia. I'm not ignorant so yes I know bout all the political staffs but why must bring it ingames? I have never ever seen a malay player insult the chinese players whenever they say them using chinese words. Usually our chinese friends defended us ingame like lanC back to them lol but hey..I knot its just a game and I will never remember their nick after the game is over so me and my fren will ignore the insults but sumtimes it can be too much. Dont matter if were winning or losing..the lanC never ends lol.

So why is this happening in our gaming community (dota specifically) nowadays and how to rectify it? ignore it? scold back? leave game?

Hope no flame post in here but oh well I know it cant be helped
