Here's a lovely response from a straight colleague of Louise's:

Hi Louise,

I have never taken part in any kind of activism. Never have I marched
for a greener earth, or the rights of whales in the sea. Neither have
I ever taken the time to put my name on a petition for any good cause.

I am however no longer a virgin activist, so thanks for the invite. I
have e-mailed my support for same sex parents and sincerely hope that
things change to make it easier for lovely parents like you and Molly.
