Frank Herbert himself stated from the beginning that Dune is a book about the dangers of charismatic leaders. The characters are just humans and make stupid decisions and mistakes, but they affect huge numbers of people directly (the religious and political stuff - hell right up front Paul learns about hitler and asks "what was so bad about this guy, he didn't even kill that many people?"), an indirectly (the effects of severe resource extraction by foreign powers on the land and the people - even 17y.o. me could see that it was at least in part commentary on oil dependence). If you want to rant on people interpreting art as metaphorical/allegorical, at least consider if the author intended it to be such. At least then you might be able to muster some credibility.
