Nice, except that's not what you originally said.
You originally posted: Theoretically, your estate could be dissipated among people who have no blood relation to you whatsoever within 2 generations if gay marriages are upheld.
To which I replied: So what? That happens now. People adopt, decide not to have kids, or blow the inheritance before it can be handed down.
I agree that children are important, and I agree that parents' primary responsibility is the welfare of their child. But I don't consider what my children decide to do with my money after I'm dead to be that important. Even if they decide to leave it to persons who "no blood relation to (me) whatsoever."
That's too bad because one of the largest incentives we have in life is securing a better welfare for the future than the one we have in present.
But since you won't be around to see it, I guess it doesn't matter.
