Ithink this might be a hyperbole. tell me what you think. "let us all hope the dark clouds of racial prejudice will soon pass away and the deep fog of misunderstanding will be lifted from our fear-drenched communities…"

Hi Nico 

I would say Metaphor for this one.

A hyperbole is an exaggeration, but a metaphor means comparing something (without using like or as) figuratively, not literally.
So I'm thinking "dark clouds of racial prejudice" and "the deep fog of misunderstanding" are metaphors.

A really good tip is to use things associated with nature, for expample maybe include the name of a tree species (like oak, ash, fir, elm, birch...) or the name of a plant or flower as well (orchid, rose, daisy, lavendar, poppy...) and for the second part use something like hills, -shire, dales, vale/valley... I hope you have a nice day too :)
