We talk in circles here and elsewhere about the definition of "feminism". This recent link is one example.

To whit: a feminist believes in X (sometimes), and not-X (sometimes), and is completely indifferent to X (sometimes).

Substitute X for whatever topic you care to think of, from suffrage to gerbil autonomy.

This makes the term "feminist" meaningless when used to represent a position on X because "feminism" covers all possible positions related to X.

What, then, does "feminism" really mean? IE: what does a feminist believe which a non-feminist does not believe?

Based on my years of observation, this is the closest I can come:

Feminism is the belief that individual, family, community, government and society attention should focus, primarily, on post-pubescent females and their concerns, with only cursory attention, or none at all, given to others.

The above definition is consistent in every issue we discuss here on /r/MensRights, from the draft (mandatory for males only) to the subjugation of men and children in family court. The above definition explains why any perspective which draws attention away from women is antithesis to feminism -- indeed, why such perspectives are considered misogynous in the minds of feminists.
