Spock has been gay for a long, long time. You obviously need to catch up on your fanfic.
As for Zachary Quinto, perhaps it would be appropriate for all of us to mind our beeswaxes until such time as the guy decides to share his private life with all of internets fandom. Yeah like he's that dumb.

He should just tell everyone he decided to become a monk.
I've assumed he was gay since I first saw him as Adam Kaufman on season 3 of 24. But maybe Adam Kaufman the character was just gay.
That's what I thought! I was intrigued by the notion that
24 just up and decided that one of the CTU employees should be gay, without integrating it into the story at all. After all, the fact that, say, Edguh is straight (???) wasn't a plot point in the story. Now I wonder if Quinto just decided to do that on his own initiative.
In that case, can we try to figure out what Karl Urban has for breakfast? Much more important!
Was it Zachary Quinto?
Bad me, this is how rumors get started...
