Actually, I see the angry, self-hating, hyper-religious types as the angry group. Afterall, you are a part of the group that launches multiple "Darwinism hurts my feelings" threads where you seethe at everyone who doesn't share your flat earth worldview.It's not that anyone is stopping them. It's that their religion of Darwinism is taught as part of the curriculum. After school clubs are usually for activities that are not.
Still there are Spanish clubs, journalism activities and mathletics so why not a Darwin club?
Darwinian are often very angry people so maybe the club could be kind of a support group.
