We now have the benefit of hindsight of what Hitler and his system ended up doing, so when we hear a Hitler speech today, we know a lot more than the crowds who were listening to it at the time did; this causes some bias in answering this question honestly.
It is true that his speeches are hardly ever boring. He was able to switch between a calm and an aggressive speaking style depending on what was fitting for what he was saying, sometimes within a very short time. This is true of some, but not all, other politicians too.
For an ordinary citizen, absolutely. Most topics in the world, I have no opinion on, or I have the opinion that there are good points on both sides, or I have the opinion that one side is right about one thing and the other about another, or I have the opinion that one side is mostly right but the other also legitimate.
Politicians meanwhile are more-or-less required to have opinions about most political matters (or at least be able to say that they stand for them even if they don’t internally hold them). They will have to vote on them after all, and voters expect to know what they’re going to get on nearly all matters.
