I agree with this, except that the latter is BS. I find it disrespectful to call a creator's canon "fanon" in the end. Creators make things so for themselves too. It'd hurt me somewhat if ppl didnt, at least, respect the original concepts/relationships. Canon ≠ fanon https://twitter.com/thatsaltybobcat/status/1254620478171480064

Canon always deserves that high regard. Yes, it's still fiction and everyone can ship whatever they want. But you should know that creators create for themselves too. Thats why, for example, Chaggie is canon and not Charlastor or Radiodust or etc. Viv wanted it to be that way.

The person who made the text post responded to my QRT, but via a post and not a direct response to this thread. All right, thank you for clarifying what you meant.
