Can you tell me how this answer violates yahoo answers community guidelines?

Someone must be just pulling your legs. Its a perfectly understandable answer with no obsenity what so ever. Must be some homophobic douche who got startled by the word "gay" and probably did'nt even read the rest of what you wrote. I think you should ignore it or maybe fight back. I think there is an option for that. If you get a link in your email it might say something like give us a response as to why you think you were'nt being obscene. But I would suggest that you screw it. Its not worth wasting your time over :)
