Mothering would fall into the category of what I'm talking about. I'm talking about different situations: one is on a personal level and one is on a larger scale. On the personal level it could be someone speaking out for you when you don't wish it, like mothering or jumping in to interpret when you haven't asked for it.
On the larger scale it would be someone who claims to speak for a group you belong to but you don't wish to be lumped in with that person. For example, when the Anti-Defamation League puts out a statement about how something or other affects Jews, and I don't agree with that statement and don't wish to be associated with it.
