Hitler's Jail Book

In Hitler's Book he states "There are some truths, which are so obvious that for this very reason they are not seen or at least not recognized by ordinary people." This quote means that there are some truths that are so painfully obvious that everyday people do not recognize them or pay attention to them because they are so obvious. Hitler is saying that ordinary people are dumb and because they cannot see these truths, and that only he is smart enough to see them. So basically he is calling everyone else besides him stupid. This is an Ad Hominem because he is attacking everyone rather than arguing about the truths. He calls everyone stupid and completely distracts us from the real argument which is about the obvious truths
