Biden wasn't the only one who compared the Trump inspired raid on the Capitol to Nazis. Schwarzenegger did also, in a video that went viral. He compared it to the infamous Kristallnacht, which his family lived through.
The raid on the Capitol was an attempt, organized and led by a bunch of White Supremacists, to overthrow a legitimate election. You can compare it to Pinochet instead of the Nazis if you wish. It is still a violent attempt to overthrow the government. It was inspired and directed by Trump. He invited them to Washington. He told them that the goal was to stop the counting. He certainly didn’t emphasize to do it peacefully. He even sent them after his most loyal Vice President.
That is why he was impeached. That is why he has been banned from social media platforms.
Whether they should also ban the Ayatollah, or Bashar Al-Assad is a good question.
