Then would you care to elaborate on the grounds of which you disagree?
If you argue that compatibilism is not contradictory, then that must be based on the compatibilist definition of "free will", which if I remember correctly, is something like "you act congruent with your own desires" or something to that effect. But compatibilism cannot account for why your thoughts and desires are what they are, and so, even if you act according to them, their manifestation is arguably outside of your control, and therefore, your behaviour is too.
