Liberal democracy could do with less sanctimony from the left. Trump and Brexit are reactions to deaf leadership when it comes to immigration (oh, you must be a racist), local economic collapse potentially related to world trade as in Detroit for example (oh, you must be a Luddite) or other left leaning causes such as women's rights (oh, you must be a creationist and probably a misogynist too). Liberal democracy is probably the best form of government ever developed but it's far from perfect so perhaps it's most stringent adherents would at least admit some of their own deficiencies and listen as much as they preach.
