[Cyman]

Roberts was in no way obligated to write the dissent on Obergfell v Hodges but he obviously fought for and won that right....to do what, make himself look like a fool? He could have simply voted against and let Scalia or Thomas carry the heavy water and disappeared into the background thankful for the second decision laying down a smokescreen for his retreat from the national eye. Now he has the Herculean and schizophrenic task of defending these two inconsistent decisions

[Cboldt]

There are three separate dissents in Obergfell, not a "the dissent." Each justice has the power to speak his own mind, across the board and in every case.

But you are right, he had no duty to compose a dissent; and the one he did compose exposes him as duplicitous.
