Andrea Dworkin did consider all intercourse rape, and no doubt stated so long before the author of this screed did.
Why did Andrea Dworkin worry about it? She was obviously in no danger of intercourse!
EXCEPT of course if some state chose IWAD (Intercourse With Andrea Dworkin) as their form of the death penalty....but then, of course, that would be considered cruel and unusual.
She came up with the concept to explain her lack of coitus - and lacking such decided to hate men rather than do something about it.
