No one voted to "overthrow" democracy and do "fascism," cut the hyperbole.
I'm asking what should happen in such a scenario. Should a democratic society be able to vote to nuke their least favorite city? Should they be able to vote for slavery? Should they be able to vote to legalize raping kids?
What should a democratic populace not be able to inflict upon the less powerful segments of society?
We either accept "there are some things you shouldn't be able to democratically vote for" like, say, the Holocaust or reinstating slavery, or we do not.
You added Trump to the conversation, not me.
Most Trump voters didn't. A sizeable fraction have openly agitated for, and supported, violently overthrowing our elected government.
Less so when they elect/appoint them to national-level leadership.
