Social media is a faithless lover, as Justin Trudeau learned to his pain in India last week.
From the moment he was elected in October 2015, the prime minister was the darling of the web. With a few churlish (and generally right-wing) exceptions, social media loved him. He was so handsome, so virile, so articulate, so caring and compassionate – so unlike Donald Trump. He was stylish, and cool. Did you see his tattoo? Just look at his darling socks! What colour will he wear tomorrow?
