Prepare to be offended, because this is the part where I offend everyone all at once. We recognize reactionary populism in the other guy, but not in ourselves.
I have some friends who jumped out of their chairs to attack Donald Trump's reactionary populism and saw it for what it was. It was easy for them to see that a muslim ban wouldn't stop terrorists from coming to the United States; that border security wouldn't prevent illegal immigrants from committing crimes; that protectionism wouldn't bring manufacturing jobs back to the industrial midwest.
They could see that Donald Trump was either knowingly or unknowingly giving his supporters easy answers that wouldn't solve any their problems. And yet. And yet. And yet. Those same people don't see when they do the same thing--pretending that there is an easy answer that would solve everything. Those same people advocate for universal health care, higher minimum wages, and for gun control laws that already exist. Things can be done to make society better.
Politics can sometimes play a role. But name calling and pretending that there are easy answers only prevents people of goodwill from identifying and solving problems together. You can't prevent sin. You can't repeal the laws of physics or economics. Making something illegal doesn't prevent it from happening. Murder is illegal. Discrimination is illegal. Hating people by "class" is no better than hating people by "race." Don't jump for the easy answer. It has already been tried. Just because you don't know about that earlier trial run doesn't mean it didn't happen.
