Biden is promoting solutions to problems and deescalating violence. Trump seems to promote violence- especially on Twitter. He has retweeted white supremacists and conspiracy theories hundreds of times in recent days. He has made statements encouraging police brutality and defended a right wing extremist who killed 2 people in Kenosha. Biden condemned violence on all sides, and challenged Trump to do the same. He has not.
