DA I think there are S/G fans who hate Sid/Claude. And there are certainly hateboner anons who show up when certain people post Sid/Claude.

I think sometimes it seems like there is more hate for Nate/Sid because they interact more so there are more opportunities for it to be expressed, and the Oflights fic was posted more recently so it's fresher in peoples memories.

I love both Sid/Claude and Sid/Nate but I get some people don't, which is fine, and then there are some people who act very entitled about authors writing different pairings. It's just not worth dwelling on.
