I believe xenophobia was already in the air everywhere and all it needed is a spark to ignite some explosion. Blame must fall squarely on this rogue govt. If not for opening the gates wide for these floods of FTs, Singapore society, altho not that gracious to start with, is still by and large tolerant of each other after years of living closely together in glorified rabbit hutches and enforced mutli-racial communities. True, there is a politico-economico-socio imperative to Sinicising and Injunising the country thru mass immigration of yellow skins and black skins and grey skins to pump up the GDP and dynamism here; but too much too soon is where this incompetent myopic moneyfaced rogue govt has failed. The result is increasing tension, violence, and a perception that the whole PAP apparatchik has been manipulated to favour and protect the aliens.
