@Thenomain You're not wrong, so instead I'll say this:
Everyone should have equal access to the tools used to interact with the main plot(s). Those tools should be resolved, and stories progressed, regardless of how well liked you are or aren't by staff, but rather based on your use of those tools.
If a mage, a werewolf, and a vampire walk into a plot, then their interaction with said plot should be dependent upon their actions and their abilities and their relationship to what's going on. Equal access doesn't mean the same outcomes or story, just that if I say: "The sun is shining and the sky is blue and also there was a huge explosion on Main Street," then a vampire might come and scent the blood and hear the screams of the dying. The werewolf might show up and scent who planted the bomb, and try to track them away from the scene of the crime to figure out who did it. The mage might come and magically try to reverse the damage, or see what happened.
That is, to my mind, equal access.
If I, as a GM, decide to engage with Susan The Good RPer Who I Like about her boyfriend who was trapped in the rubble, and she goes through a plot to search for him, only to find out that he wasn't even there because he was stuck in the Hedge because he's secretly a changeling and now what will happen to them?
That really doesn't have anything to do with the main plot, and it's something I want to tell on my own time. While I'm resolving the actions of the werewolf, the vampire, and the mage, I can still tell this other story as relaxation and refreshment without, I think, veering over the lines of what is ethical. The main plot isn't really affected by Susan's plot. It's relevant to HER, and it's representative of her relationship with me that I'm interested in telling this story, and she gets a good depth of character development for it too, but I don't think it's a problem either.
