By the "other side" I meant the conservative factions within academia that waged war on deconstruction, but your point still holds.
What I was trying to get at was that the opposition to American-influenced deconstruction made it real by responding to it as if it were real. And to the extent that A-deconstruction was real-ized in this fashion it became a genuine potential contained within French deconstruction, even though it was antithetical to, or at the least did not follow from, French deconstruction.
And, I guess I would see a sort of inevitability to that development ... that it would be naive to think that epistemology does not get used opportunisticallly. Subsequent hypotheses instruct the theory in what it is about ... sort of.
But again, this does not counter your main point, with which I agree.
