"which seem perhaps an acceptable form of attack on neo-Nazism?"

Interesting point M - though I for one would doubt that such notions necessarily figure in the *forefront* of such popular waves of 'folk' comedy. However I'll get back to that. I think what we might be able to say, is that what we see here, is a type of comedy being produced in the context of a continuum of such comedic belittling of a potent figure of fear, one in which the precedent was set (as you reference) during the collective 'war effort' of WWII itself.

Now back to that point. Irrespective of whether or not such notions are present in the minds of those who create videos such as the Hitler Rants, the effect however is the same. IE it reduces an 'awe inspiring' figure to a pathetic figure of popular ridicule.

This is still important today (irrespective of the conscious intent of the makers) as figures such as Hitler do still inspire 'awe' of the wrong kind, as you say, among Neo-Nazi groups.

In other words, popular waves of folk comedy such as this which tap into a tradition of lampooning powerful 'awe inspiring' political figures, diminish their iconic awe inspiring potency -and- the continuing potential political influence that the iconic potency of such historic figures may yet wield in the present day.
