Why do you dislike Ray Vecchio so much?!
RayV takes care of Benny (and it's stupid of you to be offended by a nickname for Fraser that is given in affection) and does more for him than needy RayK ever does. RayV demonstrates, over and over, that he unconditionally loves Benny, and it was obviously very difficult for him to leave him for the job in Las Vegas. RayV almost sobs over the phone when he's trying to say goodbye to Benny, but can't exactly explain to him what is happening.
RayV also shows genuine affection to Benny. Just count the number of times that he touches him or puts his arm around him - and Benny does the same to him. I hardly think that Fraser would consider him to be someone that "he could not take home" - if you mean that he's ashamed of RayV, that's wrong; he demonstrates that he is proud of him several times.
I think you really need to watch Seasons 1 and 2 so you can get a better grasp of RayV and his love with Fraser - a strong friendship that can EASILY be translated into slash. Right now, you seem like you're badmouthing RayV and dismissing his relationship with Fraser to make the case for F/K slash - but you're not very convincing.
Fandom wars never die, I guess. They just go anon.
(note: I'm baffled that they think I dislike Ray V. I'm very fond of him. But I don't find him attractive or ship him romantically with Fraser. That's... not the same as disliking him)
