Tony Pua is right about the need to reduce the size of civil servants. By virtue of his position as a MP from DAP, his political opponents are obliged to, or even eager to, seize any opportunity to take a pop shot at him; turning a technical matter into a racist, counter-productive and down right detrimental course of arguments.
Let technical people make technical decision. For those with vested interest or with skewered intention, butt out! Then again these shallow minded people are unable to debate real issues with commonsense and can only resort to what they know best, which may not be the best for the rest.
