Forgive me if I am dense, but I'm not making any sense of your post, I don't understand how you have arrived at your conclusions.
I think that calling Limbaugh a birther would be accusing the person-too-far, and the charge of birtherism will begin to lose its value.

Calling someone a birthers worked because of the nature of the information that birther staked their claims on.
The publicity brochure is a game-changer.
It supports the claim that the birthers were right to be concerned by the blockage of common information, even if they weren't positive about what the information contained. Without knowing what was being hidden, but only claiming that something damning was being hidden, it allowed the credibilty of the conspiracy theorist charge, which is what "birther" is shorthand for.
But with the brochure out there for 16 years, the birther label no longer encompasses what it once did. It's like shouting "birther" instead of speaking it. People may still try to use it, but it can be beaten back now.
