The outs he makes by striking out are already accounted for in his OBP and SLG, therefore they cannot negate whatever OBP and SLG he has at the end of the season. Yeah, but if he were making more contact and putting balls in play, some of those outs would turn into hits. Negate might not have been the best choice of words, I never meant it in the active sense. I think we are arguing semantics here. Again, you can't look at the at bats in a vacuum like that. It's a result of the approach. If Dunn makes a concerted effort to get more singles by making more contact, that's going to impact all(or almost all) his at bats. That means more of his doubles and home runs become singles and ground outs, and ultimately, he's a worse offensive player because of it. That's not to say that Dunn shouldn't try to improve, or that he has the perfect approach. But to say that "well he needs to make more contact because he'll end up with more hits" is misguided.
