The difference between trump insurrectionists and Antifa.
Antifa basically just goes around the country arm-wrestling the Proud Boys and doesn't much bother anybody else. In contrast, trump's insurrectionists have much bigger ideas, like physically attacking the US government looking to hurt members of Congress.
But they don't stop there, one of them show up in Washington last week with a carload of guns & 2500 rounds of ammunition. Unfortunately, he got there a few hours late. Meanwhile, the authorities are desperately searching for one guy who was seen loading assault weapons & ammunition into his vehicle and telling people that he was going to Biden's inauguration to "stop-the-steal".
