D-Day?

While at the convention, someone handed me a flyer embalzoned with the words “D-DAY.” Reading it, I learned that this is the rally to happen on the day the Supreme Court rules on challenge to Proposition 8, whenever in the next 36 days that might happen.  Great, I’m in!  But “D-DAY”?  Really?  

They’re comparing the day that the Court will decide equality to the day that tens of thousands of men died on the shores of Normandy?  They’re admitting defeat?
