> Everyone is being alienated everywhere because the country has a leader who is actively polarizing the populous

No. That is the fault of mass media corporations (and now, also thinly-veiled "grassroots" organizations). It's quite simple to pick and choose quotes from individuals that can be construed as offensive ("superpredators", anyone? The list goes on), craft a narrative, and put them on the national stage. This is what these organizations do, at the expense of other issues. You will not find a more powerful, more influential reason for the division this country is experiencing. It is these organizations and those who profit from them the most that are most responsible.
