My take here. Chris Geidner doesn't approve of the pro-equality protests planned for today:

First, this is not a ruling about whether marriage equality is correct or just. This is a ruling about whether the California Constitution allows a measure like Proposition 8 to be voted into the Constitution by the people. Even if there is some overriding federal claim that marriage equality is guaranteed by the U.S. Constitution, it was not raised by the parties here. Second, we have spent the past decade decrying those who demean the legitimacy of court decisions by attacking them.  It would turn that principled stand on its head to say that this court, which previously held that marriage equality was guaranteed by the California Constitution, is somehow responsible in today’s decision for “denying an entire group of people our civil rights.” Third, and most simply, this is not the righteous anger exhibited this past fall.

Dan Savage:

The anti-gay bigots said before the decision that they wanted Prop 8 upheld and they weren't concerned about the 18K gay couples who wed while same-sex marriage was briefly legal in CA. That exposes their fundamental dishonesty. If they believe, as they claimed during the campaign, that married same-sex couples are a threat to the family, a threat to children, an invitation to hurricanes and earthquakes and wildfires, and that the existence of married gay couples somehow requires homosexuality to be taught in schools, how can they be indifferent to 18K married gay couples rattling around the state? Won't all those bad things still happen?

John Aravosis:

...the ongoing existence of these marriages, with no demonstrable harm being caused by their existence, will call into question, if not outright destroy, the bigots' argument for why the state has an interest in banning gays from getting married.
