Okay, I felt this stamp wouldn't be out of place. You may wonder what I mean by this, and it is simple. It's about those people who actually care about which fictional character fucks which fictional character.
Alright, I enjoy male slash. No secret. I have a lot of pairings I enjoy because I think their personalities work or even just because they look aesthetically pleasing together. I go to some communities to read fanfiction or see fanart of my favourite pairings. Sometimes, rarely, I might even contribute. Countless others do this. I don't see any problem.
What I do see a problem with are the people who seem to think pairings are something anyone should treat seriously.
There are two kinds. You have the people who ship some random couple and will fight to the death for it, flame people who like other pairings, draw other characters getting mauled because there's another popular pairing involving one side of their OTP and said character, etc. Those are annoying enough.
Then you have the people who somehow feel that a drawing of two male characters kissing has RUINED THE SHOW FOR THEM and the artist should GET A KNIFE SHOVED DOWN THEIR THROAT because they made their favourite characters into FAGGOOOOOTS. These are more annoying, and I don't think I'll ever understand them. Why would your enjoyment of a show be hindered by someone's silly picture ?_? is it really worth saying things like 'please, just no' or that this kind of thing makes you 'lose faith in humanity'? Aren't you taking this a little too seriously? It's about the relationships of people who don't exist.
I've seen fanfictions of shows like Will&Grace where Will or Jack were paired with girls. I think it's an alright show. Despite having seen that these stories exist, I didn't write a flame to the author. I didn't stop watching the show or cry while slowly cutting myself because you have to have a completely warped perception of importance to give half a damn about this kind of thing. I just didn't read the story.
I personally like House/Wilson, for instance. It's not canon, even though some writers like the pairing. Plenty of people like House/Cuddy or other kinds of slash pairings. There are about as many retards in any fandom of House (there was a big fight between House/Cameron and House/Wilson at some point and it was all very silly) and I think this seriously impairs everyone's enjoyment of their respective pairing.
So, tl;dr: If you enjoy your pairings in peace and quiet and let others do the same we'll all be much happier in our respective fluffy, lovely silliness.
