When:
You have the world's largest megaphone.
You bring tens of thousands of hardline supporters to the Capitol on the day that officially seals the transfer of power.
You and your henchmen spend hours forcefully lying and claiming that the entirety of the national election apparatus is in a conspiracy to steal the election.
You tell them to march on the capitol to 'fight.'
You are inciting a riot.
When, as the capitol is being ransacked, you double down on the lie and continue to say the election was stolen, and to say you love them, you are continuing the riot and you are trying incite nationwide unrest.
This isn't complicated or "a matter of opinion."
