Math club died out long ago in most schools. Same with the chess club.
The ironic thing is that if they want to stamp out pro-Christian student groups, they’re going to up creating case law and/or legislation that bans ALL extracurricular clubs (since the law is “all or none” right now) including the ones near and dear to liberal ‘hearts’.
Our middle school and high school have chess club, Young Life, and Latin club, among others. One of the advantages of living in the Bible belt. :)
