Let me just be more explicit: if your software cannot be used by nazis then your software is not free software.
This is not the correct place to fight hate speech. Block the instances. Report hate speech to the authorities. Settle it using the existing legal frameworks to do so, and if they are insufficient, then write to your lawmakers.
But if you support free software, it is not the place to address this issue, by definition.
@sir Your software cannot be used by non-pro users. And you always defend that. Is your software proprietary?
@xiroux I mean, they're free to try to use it, and learn how it works
@sir Well, nazis are free to try to stop being nazis.
