DNA & Genetic Testing Sites Revealing Family Secrets

I can trust these enough to pay attention to them, but definitely do not trust them 100% (I don't think they even guarantee it 100%). I'm having one done on my father right now for fun. Funny how we cannot know who we are based on 4 or 6 generations back with absolute accuracy but somehow through the carbon dating method (I know it's a different method) we are to trust the accuracy of a billion year and hundred million year based on it. Many times we can't even point to the difference between someone who died 50 years ago versus 100. Again, these methods have some good testing (good enough to look at and take seriously when comparing to the alternative being "nothing.") but can't be completely reliable for me yet.

One example is this. 98% of Native American populations in North America are dead via genocide. The other 1% of Native Americans left won't subject themselves to the DNA tests because they feel they have been tested on enough.

Almost 95% of Latino's are mixed if not more, thus the fact that they ARE NOT A RACE and cannot be considered identical to Native Americans who (unless you're Seminole) are a race.

However this hasn't stopped Henry Louis Gates from telling people they don't have any Native American in them.

I know some smartass on here knows its based on diet and blood type or the swabbing of the mouth and can tell which places around the world the findings are most similar, and will not hesitate to point out carbon dating methods and other dating methods BUT my argument again isn't against finding these methods relevant; it is against trusting these enough to consider them factual absolutes.

Generally I don't like to talk at all about my Native American Seminole Great Grandfather bc of how many blacks and (now whites too) try to claim Native American for the sake of saying they're not black or as if being something else adds to one's status. I'll put my Sierra Leone family and African on both sides 3x over (and my black ass being black and NEVER seen as Native American) over stating I'm one tenth this or that. But, my great's name was literally Goat Tear, we got a picture, he was burned alive by the government because he wouldn't sell his 1,000 acred land and since he was crippled he couldn't escape. My family got no money from it. Knowing that and having that in the US records, I'll say if the DNA tests says his ass wasn't Native American then that's BS.
