I would have been on that distribution list and I never received that e-mail. I am very doubtful as to its origin. Keep in mind that I am not stating anything directed at you, I am only letting you know my own, direct knowledge regarding that e-mail.
I followed the links and they went to a "progressive" political site that does indeed call "same sex" issues "marriage discrimination."
As you point out, I did not write the AFA page.
