You choose to participate here instead of having face-to-face conversations. Does that mean that face-to-face discussions aren't useful? I walk on sidewalks where cars are prohibited. Does that mean that cars aren't useful? I drive on highways where pedestrians are prohibited. Does that mean walking isn't useful?

Whatever point you're trying to make, this is an extremely ineffective argument for it. You’re in “checkmate, atheists” territory here.
