Rubbing salt in the wound

The Bishop of New Hampshire announces his upcoming "marriage"

"I am certainly not doing that to rub salt into anyone’s wounds, but no
one should expect me to penalise me and my partner when these rights are being offered. “We were looking for a three-day weekend which would allow people
to travel more easily, and that happened to be the fifth anniversary of my election as the Bishop of New Hampshire and thought that would be an appropriate date. “I think the fact is my critics would find any date impermissible.”

How approriate. On the anniversary of his consecration. He's right - no date is permissible. But this date is rubbing the salt in the wound is a big way. Does his new "spouse" get to go to Lambeth too?
