Of course some might refer to you in a derogatory manner as a Mamak. Or even a Keling or si Gelap! In the early 60's when I was a student in London we would refer to those very dark skinned Negros as "Gagak". But we are all adults here and if you promise not to call me an Anwarist or worse, a paid PR Cybertrooper....I will call you a Malay....well "almost a Malay" lah!
In spite of half a century of arrogant and corrupt Umno rule the Malays are still by and large, decent, polite and respectful people.
In spite of the en mass inclusion of pendatangs, people from Kerala and Mamaks of your ilk the Malays are still the same people they were pre Merdeka - especially in the Kampongs and in ordinary households in the urban areas where ethics, morality and good manners are the norm rather than the exception.
