On this I agree.
I'd also add that fandom (or, better, I should use the word "fanon") has changed a lot in the last decade, with the social media, which doesn't help.
Up till then, you shipped whoever you wanted and it was a silent rule of the fanon that what you did in the fanon stayed in the fanon. Now... yes, people conflagrate fandom and canon and that's wrong on so many levels. There's also this need to see one's slash pair to be confirmed in canon. So, so wrong! Because fans of a certain ship go to pester the authors or pretend authors to canonize the ship. When fanon was never meant to get things canonized - it was just a "play with someone else's toys".
On Logan... Well, a man as old as Logan... On one side you'd expect him to be old-minded, and perhaps a bit of bigot/homophobic. On the other side, you'd think he tried everything, including love (or just sex) for/with a man.
But I understand your point on Logan / Daken.
If I were a Logan (or Daken's) fan I'd be very, very annoyed too.
Edit: if it wasn't clear, I'm an old-school fan who keeps canon and fanon separate.
