You know, without the crazy genocidal stuff, you're probably right. Srs.

He was intelligent and he was a great speaker. I bet he was great to talk to...but like you said, without the crazy "kill all da jeeeews" shenanigans.

He wasn't a speaker, he was a shouter. He didn't make great speeches, he knew how to get people riled up but he didn't execute any of the worlds greatest speeches. He wasn't particularly intelligent, he was charismatic, that's all. An obstinate man, but one with vision. Most policies, good and bad, were made by his buddies for his approval.
He "solved" economic problems by creating loads of short term jobs, kicking women out of the workplace so only men could work, this gave the illusion of low unemployment as people eligible for work would work, but that's because he made so many people ineligible.
He only got where he did due to his charisma and persuasiveness, but he wasn't great at addressing, more like barking.

I didn't say he was a great orator, just a speaker. Say what you will about his "intelligence" but the man (through his speeches or "shouts" if you want) pretty much brainwashed an entire country.
