Mwanandee Kindembo is a Congolese writer and philosopher. His quote is that a nation can't impose Democracy, people have to impose it on themselves.
I want to make a point about why Democracy often doesn't work in general and how the United States' founders tried to address this issue.
Here is the general problem with Democracy, which the United States has avoided. Democracy can easily turn into an autocracy of the majority where they can scapegoat the minority. There are numerous examples, but let's use India as our current example.
India is another large country with multiple ethnic groups and religions. Throughout most of its existence as a single country (since 1950), the voters have been split between different states and diverse desires, as is the case in America. This created a system in which coalitions dominated most national governments.
However, in recent elections, a different voting pattern has emerged. In many regions, voting began to follow religious lines. The 80% majority of Hindus voted one way, and the 14% of Muslims were overwhelmed. India's government then started implementing rules that left Muslims with less and less power. Muslims were ostracized and cast as enemies of the nation. The majority groups were vindicated and rewarded with control over the minority group (see Kashmir). Democracy itself was used to deny rights to Muslims. (Note: recent elections in India have begun to self-correct this with other Hindu parties competing for power.)
Or look at Iraq, after we imposed Democracy, the voting was along sectarian lines, Sunni, Shia, and Kurds. America had to establish a shared system of apportionment to maintain peace. That agreement has long since dried up.
America implemented a very different system. We have a Democracy where the voting power of the majority to ostracize the minorities is limited. We have elections for one set of legislators every two years (House) and another set every six years (Senate). We elect a President every four years. We have Supreme Court Judges for life. The idea here is that the majority would have to win multiple elections at both the national level and state level to harm the minority, and even then the Judiciary could overrule both the legislative and the administrative branches of government.
And the way we vote for President is a combination of popular votes across different states. The idea was that a single dominant group would find it almost impossible to control all the levers of power to impose its will on an ostracized minority. It has worked in the United States for so long because we have long voted for issues, not for our ethnicity. Even now, most Republicans are not voting for whites being in charge, but for the issues they promise to fix.
This has worked excellently in a multicultural nation. And when enough people try to punish a subgroup, it becomes challenging. Look how long slavery lasted, even though it was an unpopular system long before the Civil War! A minority of people and states held up emancipation for over a century. It's hard to change major laws in the United States. But right now, the stars aligned and the Republicans are in charge of all levers of power at the national level and in most state levels.
They have begun to do what unfettered rule by majority usually does: exclude other groups from power. The outlawing of Trans rights, making it harder for Blacks to exercise their voting rights, outlawing protesting, and more.
Somehow, new media has been able to divide our nation into two competing voting blocs, effectively making us resemble other nations where the rights of the majority vastly outweigh the rights of minorities. The relative size of the majority vs the minority does not matter when one party controls all the power.
In nearly all other multiethnic states, particularly in Africa and Asia - where national boundaries were drawn by outside colonizers, Democracy falls apart when some groups realize they don't have a voice in government and probably never will.
Our own Civil War started when the slave states recognized they would be permanently excluded from power. Our current ruling government is attempting to expand its own power to secure lasting dominance by altering voting rules.
The question of whether we can preserve our current democracy seems to me to be dependent on whether we can uphold our laws beyond this attempt to establish single-party rule. OR if that single party breaks into factions once Trump, a unique politician, leaves the scene. Because for the next 18 months or so, minority rights are at the whim of Republicans.
