Can you write for feminist publications if it's never a label you really ever identified with?
Third wave feminist hardcore publications like reddit and github will actively carry out seek and destroy operations the second that they learn you've compromised them.
But if you mean regular feminism like that equal rights stuff then they won't care.
It's like the difference between wasps and bees. Bees are nice and fluffy and respectful towards men. If wasps learn that you have an alternative viewpoint they'll kill you in your sleep without warning or an attempt to reason with you.
That seems to be what the journalism industry does (for most stances not just feminism). They are paid (hardly) to turn out crap quickly.
Also for feminism specifically the mostly highly paid are basically actors, because you can make millions given talks and playing video games, pretending you can't find the jump button to see batmans butt and that is sexist.
