Completely false!! The afrodescended people are from various west African nation/states who were captured and enslaved through the Slave Trade. DNA evidence has showed that! If your assertion had merit, then comparing the DNA of the Olmec people vs that of the current Afro sample would be an excellent strategy for proof of concept,

Google is your friend. Here is an article from Lonely Planet that has some info on Afro-Mexicans: https://www.lonelyplanet.com/articles/brief-guide-to-afro-mexican-history-and-culture

What’s missing in history to compliment your family history is that the slave trade happened in reverse and that they may have been on a slave ship coming from North America going to the Carribean. Many Indigenous peoples (including my ancestors) were enslaved in North America and shipped out.
It make a lot of logical sense if you think about it. Just consider how close Louisiana is to Mexico, they share the Gulf of Mexico.

Exactly right

The unpopular truth is we have always been here in all of the Americas including the Carribean. The so called Afro Mexicans are the descendants of the Ancient Olmecs, not slaves from Africa.

WRONG! Not all Afro-descendants in the Americas were initially brought by European slave ships… Lol, your knowledge is a “False Flag” Not all Blacks were slaves or brought as slaves.. You got your knowledge from a book or reading that was sourced by a White man so of course it’s going to be biased. Mexico itself has a dedicated special monument honoring the Olmec people.

It was slavery of course. Many either were brought there or escaped slavery in the US.

Read. Learn to read. But short answer black people where always there.

I belong to the Afro-descendant community of José María Morelos in the Costa Chica of Oaxaca. Yet today the community identifies as “negros” in a long-denied claim to the third root in Mexico. It’s true that these towns were made up of slaves who escaped from their masters, the so-called “cimarrones” who in turn mixed with the indigenous communities of the region. There are vestiges of this as well as a tradition that is typical of AFRICA, the phenotype is not the only thing that identifies us as Afro-descendants and there is a whole investigation. Who is misinformed is you.
