There's not a contradiction there. You can say there is no moral absolute, because absolute statements in and of themselves aren't inherently moral statements.
We're not talking about just any absolute statement. The reasoning does not support the claim.

There is no logical contradiction here.
You are making an absolute statement about morality. Statements about morality are moral statements. Therefore ... &c.
But I would grant you your argument if we distinguish between standing moral absolutes (such as the one in question) and another kind of absolute which isn't really an absolute at all (because they never quite hold ... granting your argument, e.g., it is always wrong to kill, or what have you).
Perhaps in that way both you and op can be correct.
