Note: I found Was there racism in Middle-earth? shortly before posting this, but I think that they differ enough because the other question focuses on racist attitudes, whereas this question is not dependent on the mental attitudes of beings but instead the applied treatments.

Elves and Men are called the Children of Ilúvatar because they were the two races he created, excluding divine beings such as the Ainur. Dwarves, on the other hand, were created by an Ainu named Aulë.

Are Dwarves ever treated as - for lack of a better word - second-class citizens by Elves and Men because they were not directly created by Ilúvatar?
