You don't need to know anything about the characters here to understand the satire.
"Although widely believed to conflict in every way with the rule of law, violent insurrection can be an effective approach to upholding the principle of limited government."
People who believe in limited government believe in the rule of law. Violent insurrection is pointed out to be in conflict with the rule of law, and at the same time held up to be a principle of limited government. Brilliant satire.
"when the Supreme Court refuses to exercise its Article III authority to overturn the results of a free and fair election, calling on a violent mob to storm the Capitol represents an appropriate alternative remedy."
When would a violent mob ever be an appropriate alternative remedy to a free and fair election? The people who actually believe a violent mob is an appropriate remedy would never call the election "free and fair". They believe it was "rigged and stolen". This is what makes this piece satirical; it's making the case from the opposition's point of view while simultaneously refuting itself. Poe's law does not apply. You don't need smiles and winkey faces or a /s to know this is satire.
