Exactly. I could call myself a pop star. But without a produced record, at least one widely recognized song, the aesthetic, the moves, the media, etc....that would make me delusional, not a pop star.
Being a feminist is not an identity, it's not a club, it's not a religion, it's not a statement, it's not a marketing promotion.
It's not any of those things.
It's two things primarily.
It's a political and social ideology about gender equality, first off.
Secondly, it's a choice in how one lives one's life in order to bring that ideology to fruition. It's trying out the precepts and the concepts and then sharing how it worked out to trailblaze a path forward for others.
