Parent A and Parent B

Norbizness has a great takedown of a supposedly "reasoned" argument that gay marriage hurts children. Apparently, it's a paperwork issue:

My Department of Public Health has asked whether we must re-write our state birth certificates to conform to our Court’s same-sex marriage ruling. Must we remove “father” and “mother” and replace them with “parent A” and “parent B?”

You would almost think that this hadn't come up long before the marriage issue. Except that it has. Lots and lots of gay couples have children together, with both parents on the birth certificate. I do believe that they just scratch out the word "mother" or "father" and write in the proper one. So it says "Mother" and "Mother" or "Father" and "Father".
Maybe it really is way too scary to contemplate what it means to scratch out one word and write in another.
