SINGAPORE - It is important to call out and challenge racism when it happens, but this should be done in a constructive manner so as to further the discussion, said Minister for Culture, Community and Youth Edwin Tong at a webinar on race on Wednesday (July 14). He added that a recent example of someone who highlighted a racist incident constructively was ice cream store owner Dave Parkash, 26, who was harassed along with his girlfriend Jacqueline Ho when they were in Orchard Road last month.
