Its interesting that you brought up a foreign language club, because the Esperanto movement would be a relatively wholesome association for an ex-JW. It tends to attract a lot of idealists. Instead of believing we are going to live forever in paradise, it is the movement hoping for a much humbler utopia in which everyone understands each other because they have compromised to not force an ethnic or national language on everybody but instead speak a simple constructed language. It tends to attract a lot of nerdy Unitarians, Bahais, Quakers, and Freethinkers but very few if any Nihilists, Gangsters, Religious Fundamentalists, Racists, or Right-Wing Nationalists. It isn't the most beautiful or practical language but it is easy.
Don't worry about those well behaved toddlers. Yours has a higher IQ and can kick those well behaved ones' diaper
