Well, here's the thing. lemmy.world is hosted by someone that wants to host Lemmy on their own infra. Someone is choosing to serve it out of their own good will. You created a very controversial community, and the person hosting the instance didn't want it to be on the server. That's all there is to it.
This is the same thing as being racist at someone's dinner party and getting kicked out for it. You're not entitled to run a community at a place that isn't yours. But that's the neat part: Lemmy is open source and federated. You can create your own Lemmy instance that is your own and be as anti-women on there as you want. Maybe some other like-minded servers will even want to federate with you.
