Two common points crop up in these kinds of discussions:

- what if you're part of a minority the government wants to disappear, like the Uyghur in China? DNA is indicative of many minorities. You don't have to commit a crime.

- you don't have to share your DNA, some distant cousin sharing theirs is enough to implicate you (as in the Golden State Killer's arrest). You cannot control your far-flung relatives. You may not have a choice in this kind of privacy. That's what makes DNA unique in relation to other kinds of private data: your cousin's browsing history does not implicate you, DNA however may.
