You shouldn't. See, you don't try to reason with your father about his alcoholism. Talking does not work for everyone and sometimes make things worse. Instead you can try to encourage him to come home early for dinner, to bring kids to Universal Studios or save up to buy a nice plasma tv to watch football at home. No need to say "your breath stinks", "you beat up my mother", and "you throw up all over the place". They may well be true but see how talking about it is counterproductive?
The difference though is that Sinkie chinks do not see Malays as their family, as fellow members of a collective. As a wise man once said, "We are a city. We are not a country."
