A toxic culture starts from the top. DJT's seeming enjoyment of the driving of division between parties (and even within his own) is part of the problem. He is not the only problem and removing him isn't a cure but a hopeful/forward looking leader (from either party) doing everything he/she can to positive push the people together would be better for the country.

Besides the culture wars and this current (in my opinion) backward looking view on immigration I am not sure I'd agree that the ship is sinking. Overall things are good, there is just a lot of negativity & division that I think that is being driven by profitable propaganda on both sides.

There is a real problem of profitable propaganda that the internet & unlimited media consumption has created. People get very excited over immigration and other hot button political issues and many exploit the people and the issues for personal gain.

Regardless of who the president is profitable propaganda will divide the country. The current administration validates these otherwise fringe views and magnifies the problem. DJT makes no attempt to heal the relationships between liberals & conservatives and instead really seems to enjoy driving division.
