I still don't think his comments are anti-Buffy in any way, though. He just doesn't think she loved Spike the way he loved her, which is not an uncommon view. I don't either think he's that invested in B/A. I doubt he's given it much thought.

Exactly. In Brian's universe, Buffy isn't even a secondary character. She's just an extra. A girl whose name Spike uses to taunt Angel.

It's like switching from an archive with mushy Spuffy fics to another page with snarky and sarcastic Spangel site. :)
