Hitler also rose to power through his speaking skills, people say he had exceptional oratory skills.
So did Christ, and Gandhi, and Abraham Lincoln for that matter. Anyone who can hold the attention of a large audience has to be a good speaker.
IMHO Obama is a lot closer to Hitler than people want to let on.
When you invoke Hitler comparisons, you insult the memory of everyone killed by that maniac. Even worse, you enrage the survivors of the camps even more. You offend not only Jews, but anyone who lives their life with even the slightest bit of human decency.
But that's just my 2 cents worth
That's all it's worth.
