So far as I can tell, it's a fundamental of all forms of feminism (though especially radical feminism) that yes, everyone must make fighting sexism and supporting feminism their #1 priority, over and above the actual goals of whatever businesses or groups they're involved in, and that anyone who doesn't is a women hater. You get stuff like Atheism+, where a bunch of feminist activists went into the atheist movement and declared that from then on, it must revolve entirely around their form of feminism, and that it didn't even matter if members were actually atheists so long as they supported that kind of feminism. Radical/non-intersectional feminists even tried to do the same to groups fighting against other forms of discrimination such as racism and homophobia.
