SAN FRANCISCO (CBS SF) – San Francisco’s former mayor Gavin Newsom, who thrust himself on the national stage when he legalized same-sex marriage in the city in 2004, is now demanding an apology from Texas Governor Rick Perry after he likened homosexuality to alcoholism in an appearance at the Commonwealth Club Wednesday.

Perry said he was not qualified to characterize homosexuality as a disorder, but then drew the comparison.

“I may have the genetic coding that I’m inclined to be an alcoholic,” Perry said. “But I have the desire not to do that, and I look at the homosexual issue the same way.”

On Thursday, the lieutenant governor took to Twitter to voice his frustrations with the comments.

That comment was followed up by three more within a couple of hours, including:

Newsom said it was particularly troubling that the comments were made in San Francisco. Pegged to the top of Newsom’s Twitter feed, which has 1.2 million followers, is a map of the states where same-sex marriages are now legal.
