You're wrong. Rimu has never expressed any objection to pro-LGBT sentiment and has even done interviews in regards to that. I have seen him ban people for anti-LGBT bigotry. This particular ruleset looks like a copy and paste from the retention rules that piefed.social currently has that doesn't save data from communities after 6 months. (RImu doesn't have a high opinion of meme-themed content and believes it to be a drain on server storage).

I agree all of it should be optional, and I believe it currently is anyway as instance owners can revert this.
