Van Sertima is a crackpot. You realize modern DNA samples alone repudiate most of what he believed?
Also, you say "there is absolutely no reason to trust elite white men", yet you do nothing but post conspiracies created by, funded by and promoted by the most nefarious elite white men on the planet.
You are promoting conservative, billionaire-backed talking points. Your last link was itself from a website bankrolled by the most wealthy privately owned company in America.
And these talking points are designed to do very specific things:
1. Attack any and all government policies (because the more you undermine government and the civil sector, the more freedom corporations have to exploit humans and the planet. Case in point, you posted several days ago comments from the author of the book "Roll Back", a book which literally advocates dismantling all government in favor for full privatization. You're so brainwashed, you don't even see the objectives of the people feeding you your conspiracies)
2. Attack any and all non private organizations, or organizations which foster co-operation (conservatives hate any type of co-operation, multilaterliasm or internationalism which is pro-social; see their attacks on groups like the WHO, or the UN Sec Council, or how British conservatives pushed to jump out of the European Union the moment it started shutting down corporate tax shelters and promoting environmental regulation)
3. Attack the intelligentsia of society (scientists, universities, academics etc), which typically also includes an attack on artists. Because once you destroy the brains (academics) and hearts (artists) of a society, the society is unable to correctly diagnose its problems or rebel.
4. Destroy all pro-social behaviour, all co-operation and organization, in favor for rugged individualism and anti-social behaviour. The conservative vs leftist stance on mask wearing epitomizes this. Leftists wear masks to help others, protect their fellowmen, and prevent themselves spreading germs to others. Conservatives, meanwhile, do not wear masks because they believe in hierarchies of power in which rules and laws do not apply to them, a privileged minority.
There's a reason the Democratic Party in America, a party that has been trying to get free health care to all Americans for 60 years, is for vaccines.
And there's a reason why the Republican Party, a party that has been filibustering and blocking all attempts at health care reform, is anti vaccines.
Leftists, and to a lesser extent liberals, want to help everyone.
Conservatives, meanwhile, want to preserve privileges for a minority (usually the wealthy, or whites).
Leftists, and to a lesser extent liberals, want to flatten society and make it more fair.
Conservatives, meanwhile, want something more tall and pyramid shaped.
And so when a global pandemic hits the world, your leftist/liberal instinct is to work together for the benefit of everyone.
Your conservative instinct is to undermine this at every turn; destroy all examples of pro-social behaviour, lest it catches on. And that's the real virus conservatism has, throughout history, sought to crush. Not covid, but people working together for common interests. It seeks to crush hope.
EDIT - incidentally, you're anti Jew nonsense is literally right out of Hitler's Mein Kampf. They've got you resurrecting 1930s Nazi talking points.
