Martial Arts vs. Religion

Most martial arts have some type of spiritual basis, some stronger than others. This is usually a connection with a person's inner self rather than with some outside deity. 

Some martial arts have a strong religious connection while other have no religious connection or have virtually eliminated any previous religious connection. Even for some martial arts that had strong religious connections in the past, the modern practices of the arts have eliminated the religious connections and instead concentrate on the scientific combat aspects.

Most martial arts in the United States, including Taekwondo, do not have any religious connection but that does not prevent some zealots from finding a connection. They find what they believe is evidence of the martial arts being some sinister Eastern plan to undermine Western religions. There is no way to argue with zealots, they believe what the believe and they reject anything that challenges their beliefs.
