Just using “cocksucker” as an insult is in itself the problem, regardless to whom it is directed. As an insult directed at a man, straight or gay, it relies on anti-gay attitude to “work.” This should be fairly obvious if you think about it a moment. Saying “Aw, I didn’t it that way,” doesn’t solve the problem.
So I assume that you boycott Deadwood?
After all, the word “cocksucker” is used frequently.
It’s an insult, irrespective of the gender or sexual preference of the person at which it’s directed.
By your logic, no insults would ever be allowed, because someone’s always gonna be insulted by it. Can’t call someone a jackass. The asses of the world (in the biblical sense) might get touchy. Can’t call someone a jerk. Too close to circle jerk, so calling someone a jerk implies that there’s semen involved.
Dude, get over yourself.
No, I don’t get any of the premium cable channels.
I would not use “cocksucker” any more than I would use nigger, kike, spic, fag, or chink.
Different strokes, I guess. I wouldn’t use nigger, or any of the others you just mentioned. However, I see nothing wrong with using the word cocksucker. Some women do it. Some men do it.
And now back to our regular program:
Not really an insult, but I repeadedly “Shhhhsshhh”'d Drew Barrymore at an Arclight showing of Donnie Darko: The Director’s Cut. I don’t give a damn if she was an executive producer, she can still shut the hell up.
I was walking past Pasadena City Hall about three years ago, walking around a film setup (very common around here) when I came across this guy standing just outside a “Star Wagon” in sweats, chain-smoking and yelling at a rather cute young lady; something about how he wasn’t “going to act with a fucking bird, it’s not in my fucking contract, and I’m not going to fucking do it!” I recognized him as Val Kilmer, and I’m guessing the girl was some lowly production assistant (who are kept around mostly to be abused by the director and cast). I considered saying something, but figured it would just make things worse and couldn’t figure out anything clever. In his possible defense, I think he was filming “Wonderland” (about the Wonderland murders) and was doing his Method-ish best to portray legendary scumbag John Homes, so that might have had something to do with it. I don’t know what the deal is with the bird; there are no birds in the film, and as far as I can tell, no scene in that area, so whatever they shot must have been cut. BTW, Kilmer is not, as claimed, over six feet tall; I doubt that he’s any taller than I am.
I once sat in the same row with Carrot Top. I desperately wanted to insult him, but there was an older lady in between us and it was a short hop from Phoenix to LAX so…I didn’t. Talk about your missed opportunities.

He was probably thinking, “I’ll show you… Wait and see just how much licensing & endorsement mileage we can get out of that single, even thirty years from now!” 
The guy who calls himself “Justin Space” has a catty story about brushing off a flirtatious Alan Cumming. (Site NSFW. Scroll down to 11.04.04)
Not an insult really, but here goes…
I was down the shore in Wildwood, NJ back when Step by Step was really popular. Everyone was talking all week about how Staci Keanan was at our same hotel. My whole family was really excited about the prospect of seeing her, but I really didn’t care much either way.
One day I was standing outside my hotel room door and who walks by but Staci herself. My aunt was stumbling all over herself trying to fingure out what to say to the girl as I’m bugging her for a towel.
My aunt tried to ignore my requests while at the same time telling me who she was talking to. I responded with a flippant “Who cares? Where’s my towel?” Being a huge fan of her show, I know exactly who Staci was as soon as I saw her. I never saw the point of getting all flustered over a celebrity.
My aunt was NOT happy and I don’t think Staci was amused either.
Ah…Staci Keenan…one of the girls I’d slit my mother’s throat for…
Don’t know if this counts, but I once pissed off William Shatner.
Back when I was twisting wrenches for a living, ole Captain Kirk was one of my customers. One day I had to change the turn signal switch on his car. He sat in the passenger’s seat and we made small talk as I worked. Overall he is not a bad guy.
Anyway he complimented me on my manual dexterity, and I responded with, yeah if I get any better, you would have to hire me to fix your starship.
The temp in that car dropped about 20 degrees in less than 1 second. The captain was not amused. Made me glad I wasn’t wearing a red shirt.
