Amid rising online racism against Indians over H1B visas, world's richest man Elon Musk responded to an alleged supporter of US President-elect Donald Trump who criticised Musk's support for the visas. "F*** yourself in the face. I'll go to war on this," he said. "The reason I'm in America...with [many others] who built SpaceX, Tesla...is because of H1B," Musk added.
