Correct. If anybody struggles to take some lighthearted banter then they should learn to ignore those posts. If anybody believes a particular poster is continuously posting in a way that they believe is no longer banter but trolling, they can report the post and a member of the mod team will decide if any action needs taking.I think you massively underestimate how large a part of peoples "supporting" is trying to wind up opposition fans. Best to try and ignore it as much as possible because the mods have little issue with it.
And if anybody wants to discuss this or any of the rules further we have the forum content discussion sub forum where this can be done.
