Which can be answered with a simple "get lost".

edit: Since some people seem to disagree, why not? I fail to see how its any more complicated then those two words. You put in the effort to organize the bookclub, you have the prerogative to say who can participate. If you dont like that make your own bookclub. Forums have thrived on this concept for decades and it only got complicated once they became business enterprises.

Maybe to phrase it more broadly outside of the organization aspect and for general social interaction. You dont have a right to be part of a social group or go to a certain party. If I dont like you I likely wont spend time with you.

Now I realise there are multiple people in this thread but the bookclub went from:

"My book club will not be a safe space, it is open to everyone who reads the book"

to:

"Behaving like a decent human being is an implicit, obvious rule."

to:

"a simple 'get lost' [..] you put in the effort to organize the bookclub, you have the prerogative to say who can participate "

Yup.

This is a way any and all small-scale social interactions work, and have worked since forever. Pushing a CoC onto this is trying to override the natural way small groups of people form, replacing it with a formal structure that's not fun for anyone except people better at lawyering and - to borrow FakeComments's excellent term - social LARPing, than actual interpersonal skills.
