Our country was born out of a violent attack on the government at the time, and something tells me our FF's wouldn't be averse to such today.Do you think freedom of ideas makes all ideas equally valid? Some ideas are a clear and present danger. The idea that intimidation through a violent attack on the capitol is a good way to determine the outcome of our elections is a clear and present danger.
IOW, to copy the thrust of your idea, do we think that every US administration is equally valid to stay in power? The idea that the POTUS can demonize nearly half of the citizens as enemies of the country is a clear and present danger that must be stopped now.
