Actually, I think YOU need to go and read about other cultures and people. People in Pakistan and India would be offended by your behavior. People in the US/Canada/Europe would be offended by your behavior. You and a small subset of the South Asian expat community in the UK/North America are the ONLY people who think this is remotely acceptable.
Frankly I had no idea my approval mattered so much to everyone…ironically, it’s actually oddly flattering.
