The Right talk about unity is always in response to the Left-Wing divisiveness of the sort I mention above. They don't claim first and foremost to be inclusive like the Left, unless they are responding the Left's accusations that they exclude people. The Left is always talking about how they are the "diverse" party that unites all the races, ethnicities, and genders. That is the essence of their platform. The right doesn't do that, again, unless it responds to the divisive message of the Left. They mainly talk about being globally competitive, family oriented, freedom-loving etc.
My point is that we are bound to demonize somebody. So let's stop pretending that this is somehow avoidable; and let's do our research and lift the politically correct filters, so that we can demonize the right people - WHOMEVER they turn out to be.
