It's not an implication. Slash is, by definition, a relationship between same-sex characters. Or if you want to get nitpicky, between two men (separate from femslash, which is the same but between two women). You said "slash", so there's no other way to understand it, because there's no other definition for that term. If you simply mean that you don't like any pairing that wasn't seen explicitly in the show, that's another thing. But there are hundreds of novels with non-canon romances. In fact, if a novel wants to do anything significant in terms of romance, it's almost always with a non-canon character.OK, first off, you're making a BIG leap by assuming I was only talking about same sex relationships. And I don't appreciate the implication.
And the thing about subtext is precisely that is in the eye of the beholder. You may not see subtext, but it's obvious that thousand other people do. So it can never be "in direct opposition" to anything. Not in the same way as saying, for example, "Orions have red skin" or "Khan was born in the 16th century", which can be directly verified and is not open to interpretation.
