How are these two not related? Would the mob have followed his entreaty if they hadn't been fed this apocalyptic story about the election being stolen?
Those two things are inextricable linked. Each is part of the means Trump incited the violence on that day.

They are not. This is like saying a murderer lifting a gun, and then shooting his victim, are different issues.

Not that that is what's going on here, but why? Why are we supposed to look at him piece-meal? How we judge literally everyone else is by the sum total of their actions. Why does Donald Trump get the special treatment of hermetically sealing his different behaviors in how you judge each of them?

Of course they do. If you think the election was legitimately stolen, you'd be open to a lot more action than if not. Motives and goals inform actions. They're crucial context for judging actions. You can't condemn the violence in the Capitol without condemning the lies that gave rise to that violence.

Umm.. yes? You keep trying to say that the truth or falsehood of his elections claims don't matter. Then you have this paragraph that indicates otherwise. Which one is it?

That's not even remotely true. Governments are subject to any number of checks and balances that do not involve force. Heck, foreign governments exercising colonial rule have been excised predominently on the strength of non-violent resistance multiple times, so its batshit insane to make a claim of this nature.

Then what the fuck does this mean?

I don't either, but dragging out and executing Congress was never going to be bloodless. Now, however, anyone who tries it will have to fight through a rapidly-militarizing district, into a heavily-fortified building. What could have been accomplished with ~500 dead and a newly elected Congress will now require a multi-day battle and thousands of casualties.

Yeah, that's encouragement. If you don't want it to be harder to execute members of Congress by mob violence, decrying measures to prevent that makes no sense.

This is about as nonsensical a statement as is possible, if you're not "encouraging an armed uprising against the government".
