It's very thoughtful and well written, and is succinct, yet comprehensive.
I have a tendency to want to try to keep things as simple as possible when I have a specific goal, and belong to, and work within, a group with the same specific goal.
Expressing bigotry toward other members of the group creates unnecessary obstacles and is an obstacle in itself, fully detracts from constructive struggle, and can only bring about stagnation, regression, and futility. Bigotry is totally destructive; no positives. There is only loss in becoming our own enemy.
Unwarranted infighting stemming from prejudice, OC nitpicking, and engaging in Oppression Olympics within the group sucks energy from the struggle and moves the group backward, further from the goal. This is self-defeating, and is a useful tactic for those who have become comfortable in, and wish to remain in, the role of eternal subordinate victim.
Every woman who recognizes the reasons for struggle and subsequently desires to participate in the struggle is important, and should be honored, respected, and accepted as an equal member of the group.
We then individually and collectively work to achieve our goal, moving forward, supporting each other along the way.
Just my POV, and I'm extremely ignorant when it comes to feminist theory, so what I just said here might seem naive and silly.
I really like the ideas behind third wave feminism as described by the author of the piece mentioned in the subject line of this post. It seems to be a very fresh, tolerant, and progressive way, from what little I know about it; intersectionality seems so sensible and constructive to me.
