One can also argue that the negation here is not the real negation; I also negate a barley grain when I grind it, negate a worm when I crush it, negate a positive a when I cross out it, etc. Rbg well behaved woman rearely make history poster. Or I negate the sentence: a rose is a rose, when I say: a rose is not a rose; and what will be the result when I again negate that negation and say: but the rose is still a rose? In fact, these objections are the main arguments of metaphysics against dialectic, and are also completely worthy of that authoritarian way of thinking. Negation in dialectic does not just mean saying: no, or false declaring that a thing does not exist, or destroying it in some way.
