If you think that an astonishing coincidence has happened, you had better show some reason to believe it other than just saying "perhaps there will be an astonishing coincidence".

I didn't mean it as a coincidence. I meant that if you're OK with adult voters, then you should be OK with kids parroting adult voters.

However, you have a good point about the possibility that poor voters might affect their children disproportionately. I can only respond that the same might be true of adult voters, but ... yeah, there is definitely something to think about there.

It doesn't work perfectly. That's far from the same thing as not working at all.

It works worse, as far as racial bias goes, than having the 18 year old age limit and nothing else.

As I believe I pointed out elsewhere, there is more to life than racism. We are, in reality, talking about a tiny bias here. What kind of distortions are ageist biases producing?

Not to mention, in a racist world, oppressed minorities have lower life expectancy.

(Also, well ...I feel uncomfortable just typing this, but the thought occurs that if the best test you can produce is racist, then maybe you should be updating the possibility that racists were onto something.)
