Clive Barker.
Only because I was a big fan of his books when growing up and when in one introduction he described attending a fancy-dress party with his boyfriend I took a double-take.
Yeah, I had a sheltered upbringing… 
I won’t claim to have called Ms. de Rossi, but the one time I watched an episode of Ally McBeal she was the only woman on the show I found attractive. VERY attractive. So if I’d had to pick one woman from the show to be a lesbian, she’s the one I’d have picked. Much later when I heard she was dating Ellen, I was like “Alright, go Ellen!” 
He’s already been mentioned in this thread, I was pretty surprised about John Mahoney.
On the other end of the Kinsey scale, I was surprised to learn that Pearl Jam bassist Jeff Ament is straight. I’m a longtime Pearl Jam fan, and for about 15 years I for some reason had the idea that their bass player was gay. But a year or so ago I read an article about some charity work he’d been involved in and it mentioned his long-time girlfriend. Huh.
No, lots of us look at the world that way.
Rank as rank as rank.
Tom Cruise and John Travolta, okay, I’m with you, but I ain’t seein’ George Clooney. He strikes me as merely a perpetual bachelor, content to bang women once in a while but otherwise content to go home alone.
On Henry Rollins:
I’m the first one to admit that he looks the part of a stereotypical hollow, posturing macho shithead, but that doesn’t mean he is. My take on him is that he is blessed with an extremely butch face and takes pride in his hard-earned chiseled physique. He works hard to maintain it. Why shouldn’t he be proud of it?
You’re shitting me. After Fight Club ?
While I don’t think he’s made a big deal of it…no big announcement or cover of the Advocate, for some reason people are shocked to hear that CNN’s Anderson Cooper is gay.
I guess we like our TV anchormen straight…
I always thought he was the only one who didn’t know he was gay. He’s always just refused to talk about it.
George Takei was the shocker for me. I, only knowing him as Sulu, had never even considered the idea that he was gay. Having seen more of him since he came out, It is quite clear to me. I was just stunned when I learned this, though.
Neil Patrick Harris was definitely number two. Again, I have no real reason to assume anything. I just didn’t realize he was even “rumored” to be gay.
Portia De Rossi. I have only seen her on Arrested Development, where she is not only straight, but pathetically so.
Dan Butler, who played Bulldog on Frasier. To be fair, he was out of the closet from the beginning of the show, but I had no idea. No gay man has played “heterosexual pig” better. No, I have not seen NPH on How I Met Your Mother.
Edward Mulhare. Reginald VelJohnson. Luther Vandross. Raymond Burr.
Her marriage broke up when she hooked up with another married guy on her “Men In Trees” set.
Honestly, I don’t really care what her sexuality truly is, but after that book where she claimed to be the reincarnation of some celestial being (or some other such nonsense), I don’t trust a word she says. I think she’s desperately seeking attention and would claim to be attracted to monkeys if she thought it would get her some pub.
I’m no media escort; but I met him at a book signing/reading once. He seemed charming and witty, even if a bit tipsy from the bottle(s) of wine he had before his talk. He held a Simpson’s trivia contest before reading from his book. I won and he gave me a box of store-brand animal crackers that he picked up from the nearby grocery store that afternoon. He answered questions after his reading and then signed books and chatted with people without seeming to be bored or unhappy about it. Again, it might have been the wine.
I’m still surprised that Lyle Lovett isn’t gay.
Ray Boltz. I grew up fundamentalist, so I not only knew his name but can still sing several of his songs more or less by heart, no matter how much I might wish I couldn’t.
“Thank you… for giving to the LOOOOORD!”
Well, I’ll be damned…
I followed the link given on page 1- the one listed there that made me go “huh” was Will Geer, aka Grandpa Walton. I didn’t know that. Didn’t know about Graham Chapman either. I went to the Rs to see if Keanu Reeves was included, but apparently not.
John Malkovich and John Wood are two I was surprised to learn were straight. Both pinged my (admittedly faulty) gaydar.
Perry Mason was gay?
Man, the denial in my grandmother’s house when it came out that Rock Hudson was gay was thick. My grandmother ranted about the press for a week solid. When I told her Liberace was gayer then a fairy ring she about took my head off. But when I suggested Errol Flynn wasn’t exactly the poster boy for Straight Americans, she wasn’t surprised at all.
I remember once when she & Ellen were first together, they were on Oprah. Anne insisted that before she met Ellen she “wasn’t gay.” Good ol’ Oprah tried to help her out by saying something like, “you mean, you didn’t know you were gay,” and Anne insisted that no, she wasn’t even a little bit gay and never thought of women that way until she met Ellen. And Ellen just sat there like that was the most normal thing in the world. It was weird.
:smack: I can’t believe he’s not the first person I thought of when I saw the OP. I saw him in concert a few years back. “Thank You…” is one of Mom’s favorite songs. (I prefer “I Pledge Allegiance to the Lamb”- along with the video of the Dad telling his son about how society turned anti-Christian right before the Dad is taken out to be martyred.) And yeah, the coming out was a shocker.
Video is here.
