What I fail to understand is why union organization doesn't happen quietly until they have a large percentage of people agreeing to join.

Is this something that's ready for disruption, like a social-media site for unionization resources and to facilitate unionization?

Or have a company not hire you, because you have a marker for an 'expensive' illness, and they want to keep their benefit costs down, so they only hire people with favourable genes.

You should be concerned about the uses you haven't imagined, rather than the ones you already have. DNA is what makes you, YOU, and once that information is outside your control, there's nothing you can do to change it.

I'd purposely drive way over the limit to get buzzed by a fighter jet.
