Answer: Everything about the inauguration was riddled with distrust and danger, even to the point that the National Guard wasn't allowed to have ammunition in their weapons out of fear that the soldiers may fire upon the president. The division is so extreme that the men and women that are supposed to protect the president can't have the means of protecting him out of fear he will be shot, so if there is massive distrust with the military and the president, his position is build on loose sand instead of stone.
For the inauguration, instead of a pastor, priest, or other Christian figure, he was instead blessed by a Jewish Rabbi, breaking the tradition of having a Christian bless the president on the inauguration. Even Donald Trump, the 45th President wasn't present for the inauguration, so there's already a breach of tradition in that aspect.
With the division aspect, there may soon be extreme civil unrest that may lead to war in the future, either it be right wing paramilitary groups against the government, left wing paramilitary groups (Antifa and/or BLM), or even both.
In the end, I think that this may be the last election America will face, the future is clouded and foggy, and uncertainty is everywhere. In every major empire to exist, every 250 years or so a major event happens, either if it's good or bad. And America has reached the age of 243 years old, so it's very much due on it's historical event. Whatever the future has, we must prepare for.
