Before writing such articles perhaps one should check their facts. Metal does attract lightning. Icons in the air collect around metal that is grounded. That grounding enables a charge to build up as a result of an opposite charge in the clouds. The higher the point and more conductive the material the stronger the collected charge becomes around the metal object. Due to the dependence on icons in the air, movement of the metal even if intermittently grounded (walking with an umbrella) greatly diminishes the effect. Ever wonder why lightening occurs when tornados are on the ground? The movement prevents strkes from further away.
