I have not called for her to shut up! I've just been commenting about what she has said.
Then what does "she protests too much" mean?
It means that I beleive that being called a slut, bitch or **** does get under her skin even though she said that it does not. If being called those things truely did not bother her then she would not have gone on such a rant about those words. I could be wrong, it's just my opinion.
I don't think that's what she's saying; looks like she's saying it doesn't mean what the ad hominer thinks it means.
Even if your hypothesis were true, how would that boil down to "protests too much"?
And how much is 'too much'? Why is it too much?
