The facts appear to be these: The Baker's Dozen, an all-male (but not exclusively gay) chorus from Yale was asked to perform at the house of Reno Rapagnani, a retired SFPD officer and department attorney. The host of the party, Leanna Dawydiak, told reporters that some boys started harassing the chorus after midnight. Specifically, Richard Aicardi is said to have made comments like "you're not welcome here," then called some friends and said, "I'm 20 deep, my boys are coming."
Dick Aicardi also apparently called the singers "fags," which can be a term of affection when one gay man uses it to refer to another. No definite word yet on whether Dick's is a friend of Dorothy, but we have our theories. Honestly, who says "my boys are coming"? That's totally gay! Also, it's weird that a resident of SF would say "you're not welcome here" to gentle, artistic young men. But then, the 7x7 crowd always has lived in a fantasy version of San Francisco.
So then a bunch of kids beat up the chorus -- surely, an epic and honorable battle. Five to seven assailants per singer, reports KGO, which seems totally fair. Four attackers were detained when the police showed up, but then they were let go. That also seems totally fair. No evidence was collected, not even photos of the abuse -- KGO has some photos of the aftermath that were taken by the party's hosts. The SFPD's Sergeant Gittens, whose last name rhymes with "kittens," told reporters, "you want to have a complete, thorough investigation." Yes. Yes, as a matter of fact, we do.
