It isn't the decision itself, so much as what they said, and the implications that what they said has for the future of this nation.

The court took sides in the culture war, just as Scalia said, and there will be no end to the flood of lawsuits and assaults on societal and cultural norms now.

I don't see this decision as an assault on societal and cultural norms...but rather a confirmation of them.

The great majority of Americans simply don't want the sex police going into the bedrooms of consenting adults to arrest them for things like adultery and homosexuality.

I don't think this will, or should result in a flood of lawsuits you describe above.
But time will tell if I am wrong.
