The added division from the liberals, and Obama and HRC supporters, in the public and those still on US govt payroll. They made their goal public, take down president Trump and Washington DC.
This division is added to the ones existing from the Obama and previous administrations. BLM and Anti Trump protests and riots happened during Obama's presidency. President Obama did nothing to stop or even reduce this racist claimed division.
There is a division on a 40 plus year SCOTUS decision Roe v Wade. This is a social issue just like homosexuals, and race. The government has no power to change human nature. Yes, they can pass laws, but human nature as evidenced in prohibiting Alcohol couldn't be changed by an amendment to the constitution. It was so ineffective that they had to repeal the amendment.
Affirmative Action and busing didn't change the race situation in the US. To support that statement look at the rampant rise of protests and riots based on perceived racism.
Party loyalty has divided the US since they were created in the middle of the 19th century. It didn't get better, it actually got worse with every decade. The two parties, the democrats and the republicans have diametrically opposed ideologies on how to run the United States of America.
This has not only resulted in congressional gridlock, but also allowing the Executive Office to assume the duties that were given to the Legislative Branch.
The name of our country has become a misnomer, in that it is more accurately the DisUnited States.
The division also is made on social ideology, and the SCOTUS made some really bad interpretations of the US Constitution to support the liberals over the rest of the country. The root problem is the division, as the underlying issue cannot be resolved by the government?
The Civil Rights Amendments 13,14, and 15 were focused and made solely to protect the freed black slaves from ironically the Democrat Slave State Congresses. They wanted to make sure the democrats wouldn't persecute the freed slaves in congress after the Civil War.
Neither the 13th or 14th amendment gave women the right to vote. Today the courts are all over deciding Constitutional cases using the 14th amendment. But if it was really what they say it is, then Y did it need the 15th amend to allow the black MEN to vote? and Y did it take the 19th amendment 50 yrs later to give women the right to vote.
Final answer Social, Political and other assertions are continuing to divide us.
