Structure Analysis

Hello Teachers . . .
I'd love to ask about the function of every part of my sentence. (I don't know how to call it)
Here's the sentence:
"Some still prefer to see the United States as a 'melting pot', perhaps to minimize the differences and the diversity that exist"
Some = subject
still = adverb of focus
prefer = verb
to see the United States = direct object
as a 'melting pot' = preposition complement
perhaps to = transition
minimize = verb
the differences and the diversity = direct object
that = subordinate conjuntion
exist =verb

Help me guys . . .
