Why are some people so heavily invested in trying to shove people into 'true feminist', 'false feminist' boxes?
This.
sigh
There is no single authoritarian doctrine on feminism. Even within those who do centre women.
It would be really counter productive for feminism to become so narrow that it no longer allowed for debate, disagreement and discussion.
We are all wrong at times and the best way to explore that and help others see things in a different way is through conversations. People will only change their minds if they are allowed the time and space to come to their own conclusions. Getting obsessed with thus idea of purity tends to alienate and entrench and doesn't achieve the goal you want.
Ultimately the strength of an argument should always speaks for itself rather than someone being told 'it's the right belief' if you are a feminist or whatever political view it happens to be.
It is healthy for there to be disagreement to an extent for this reason.
Not to mention women do see centring women in different ways. They have different priorities and considerations. Sometimes in focusing on one thing you miss how it disadvantages another group of women.
Then there is a range of views within coming from a pragmatic approach and a purely ideological one.
Both can absolutely centre women, just disagree in how that's achieved.
