As someone who has spent time in that 'city-state' I can confirm that not being east asian will make you a target in the eyes of the majority who have vilified foreigners as job-stealing parasites while the multinationals they work for try everything to hire locals and hire the foreigners as last resort. This then makes sure there are multiple cameras ready to capture you breaking any law, local people trying to test you by shouting in public or pushing you in the way knowing full well that any opposition will be documented, colored as entitled aggression and will be used to mount public pressure to make an example out of you. Source below of what happened to a white women, just add biases against south and south east asian men to the mix and I can tell you the image of singapore projected will not match what people feel when they live there.
