Balticon code of conduct

With Balticon coming around again, I took another look at their code of conduct. It still has some disturbing features, and I'm not going, although it's within a day's driving distance and will likely have a good filk program.
https://www.balticon.org/policies
There is a blanket prohibition on "Slurs and derogatory comments about a person, group, or category of people." That presumably includes, just to come up with some examples, the Chengdu con chair, the Republican Party, the Democratic Party, the Russian Army, Elon Musk, Neil Gaiman, and whoever becomes the next Pope. It will be one dull convention if no one can say anything bad about any of those people!
No one seems to know precisely what Stephanie Burke was accused of, but I get the sense that it was making a derogatory remark about someone. She was let off because she was talking about her own experiences, but there's no exception for that in the code. The rule can be used to punish somebody whom somebody doesn't like, and that appears to be what happened. With the rule still in place, it can happen again.
Another curious rule: "Further, we ask that people not presume to speak for groups of which they are not members." What does "speaking for" mean? It's common for distant conventions to recruit local supporters to staff their fan tables. Is the rule intended to prohibit that? Why?
Does it mean people can't advocate for groups they don't belong to? That would make things even duller. It might mean that people can't claim to belong to groups that they don't belong to, which is more reasonable, but even that could cause problems. Is the concom going to accuse people of not _really_ being black or trans or whatever?
Given Balticon's rules and its past use of them, I'm staying clear.
