Morpheus you are making no sense whatever. There are no ideas in your post at all. Try making a point and defending it. I wouldn't be surprised if there was an idea in there somewhere...
It is just impossible to find it in what you wrote.
Explanation: it is a pronoun referring to nothing. What is it? What is a fragile point? Who was talking about "nacional socialism proganda?" What isn't true about the movie Das Boot? If one didn't get what? There's that undefined "it" again. Who maintained Das Boot was meant to be funny or entertaining? What could a phrase like "other than you to show what a misery it was for all that had to go through it" possibly mean? Another undefined "it." There's no there there.
Agree or disagree with me, I posited a definite point, explained and illustrated it with idiocies from the movie. Your post not only did not respond, it was irrelevant to the English language itself. Put one foot in front of the other and walk!
