What is this referring to?

How dairy cows need to be pregnant in order to produce milk, so they're artificially inseminated and kept pregnant throughout most of their lives?

Nah.

For one, I don't like a term that's supposed to promote equality clearly favoring one side in its name.

For two, most feminists I've met genuinely hate men and think they're owed superiority, not equality, for the treatment of women in the past.
