i get that you think your dna is private. really, i do.
but you broadcast it 24/7. it is only a matter of time until the entire planet is easily mapped genetically. we're half way there now, and a huge chunk of those people 'did not opt in'. a human can be mapped in minutes, if not seconds.
you send your genetic code out into the open 24 hours a day 7 days a week in every space you occupy and there is absolutely nothing you can do about it.
i understand not wanting that information used against you, hence all the genetic laws.... but it is public. your dna is not going to be some secret you get to keep in perpetuity any more than your hair color or marital status.
