Hi, no your sentence does not sound good. It could be better written as: 'Despite those ideas that I totally disagree with, Blablabla..' 'Despite those ideas, with which i totally disagree, blablabla..'

Hey André, No, your sentence does not sound that good. You might want to rewrite it in other ways, such as: "Despite those ideas with which I totally disagree, ..." (or "Despite those ideias which I totally disagree with, ...") "In spite of those ideas with which I totally disagree, ..." (or "In spite of those ideas which I totally disagree with, ...") Hope that helps!!!
