I am opposed without reservation. Databases can be compiled in ways that I am unable to comprehend or imagine. It is enough for me to know that others can imagine those ways. Heck, maybe I can be assessed a tax because of my DNA/mitochondrial advantages. Or not. I don't know what I don't know - and I'm speaking for the purity of intent in mapping my genetics.
Meanwhile, as a philosophical matter, I suspect many who may desire this genetic testing would find it abhorrent to drug screen a welfare recipient.
Edit: Spelling - drat!
I notice what seem to be trends, often reflected in advertisements for programs, actions, etc., and there has been a definite uptick in the number of ads wanting to document my bloodline or have my genetics tested.
An uncle did the geneology, back to before the Norman Conquest, so I doubt any outfit is going to provide me with much that isn't already available to me. Never mind that.
I also noted the selling angle that "I didn't know where I came from" being used to nudge people toward DNA testing to determine ancestry.
Overall, though, it seems someone out there wants to build databases of DNA, which can of course, be one of the most valuable tools totalitarians and eugenicists ever had.
Nothing like being able to say this group is the untermenschen, this the ubermenschen, and thus these will be used as thrall or eliminated, these as slaves or servants, while the rest will be the overlords (if they just have the right DNA).
Sorry, but I see a future of abuse, of targeting individuals for organ donation, a thousand abuses that can and will be justified by DNA, rather than allow for people to succeed or fail based on their willingness to work hard and be creative.
So, not only no, but Hell No.
