That isn't apparent. There was an organized attempt to protest and demonstrate against the election, which people claimed - wrongly or rightly, whatever, doesn't matter - was fraudulent, and they were calling for Mike Pence to reject electoral ballots as improper. So what? That isn't "overthrowing the government" -
On what basis do you claim anyone wanted to "overthrow" the government? And, how exactly did they take action to do so? By calling for a demonstration at the capitol? By calling for Mike Pence to "do his duty" and reject electoral ballots? What? What is "the overthrow" that was attempted, in your opinion?
Aided and abetted Trump in doing what? What is "it?" You can't leave it at "overthrow the government" - you have to set out what facts - what actions - were taken that specifically constitute that "it." Otherwise, it's just an allegation, and all the people involved appear just as likely to be honestly pursuing what they truly believed was fraudulent election and the wanted to stop what appeared to them to be an illegal theft of an election. They may well have been wrong - maybe all the evidence is against them, but so what? They can think otherwise, and they can protest even if their protest is about something completely bogus. That happens all the time.
And, let me ask you this - if there WAS evidence satisfactory to you that the election was, in fact, won by clear, incontrovertible, and proven fraud - just assume that to be true - you have now been presented with the evidence of "the steal." You truly believe that it happened. Would you think it would be ok to organize a rally at the capitol and "fight" for your belief, and to call for the Vice President to "stop the steal?" I know it's a hypothetical - I'm asking you to honestly answer - if there was incontrovertible proof acceptable to you that the steal happened - would the events of 1/6 be "seditious conspiracy" still?
It has nothing to do with "will be?" He isn't President and hasn't been since 1/21/21, on which date he left office peacefully. There was no coup. There was no revolution. He left. He doesn't have to be demoted, and there is nothing to demote him to. He is a private citizen.
It doesn't seem to bother me, because you speak in generalities and pronouns. You say "this" is an idea of the extreme right. Be specific. What is the idea? That the election was stolen? Because that sure as shit is NOT an idea exclusive to the extreme right. In 2016, the Democrats - iincluding Hillary Clinton - said Trump stole the election, was an illegitimate president, and was literally installed through illegal interference by the Russians and Vladimir Putin. If they are allowed to say that bullshit with a straight face, then it's likewise ok to believe that the 2020 election was stolen. There is nothing wrong with protesting. There is nothing wrong with believing an untruth and espousing it - it happens all the time - half of Leftists political positions are bogus and untrue and damaging to the country - but they are still allowed to espouse their stupid opinions and protest in the streets about them. So, right wingers too can believe their own bullshit.
The "it" that I am not in agreement with is the rioting. I said it that day that the rioters were wrecking any chance the Republicans had at the time of achieving anything and handing the high ground to the Democrats. The idiots who breached the capitol and rioted etc should go right to ****ing jail and good ****ing riddance. That's what I object to. I don't give a flying **** who "questions the outcome of an election." How's that?
