Note
A plural that cuts against the grain. Equality is usually an uncountable noun, so the plural appears only when the word names separate, countable instances. In mathematics, each statement that two quantities have the same value is an equality. In social discussion, distinct kinds of parity can be set side by side and compared as social and economic equalities. For the general ideal of equal treatment, keep the singular.
