Extremists in Bangladesh are locally organized, capable of coordinated attacks, and part of an international movement. Extremists in the US are neither of those things. Often, Incidents in the US are chalked up to “white national extremists” based on nothing more than some murdered having searched such websites. There used to be an organized extremist threat in the US back when the KKK was active, but that was crushed. What’s left is remnants. That’s not true in Bangladesh. Extremists systematically killed journalists a few years ago. Before it was banned, the Islamist party got 3 million votes in national elections. Extremism is being bankrolled from foreign countries through schools that teach such views. There is a deep well of support for such views among the people—1/3 of Bangladeshis believe that people who leave Islam should be executed. And, finally, there is a real risk of extremists taking over the State, as happened with Pakistan and Afghanistan.
None of that is true in the US. People who say “hurr durr but Republicans are a white nationalist party” do so out of ignorance, because they have no idea what it’s like to have extremists actually threaten your democracy. And their ignorance is dangerous. It’s dangerous to a world that needs US leadership to overcome extremism. Their false equivalency and apologism undermines the people in countries like Bangladesh who continue to fight for liberal democracy and the rule of law.
