You are correct that people have the freedom to live in imaginary la-la fantasy land if they so wish. But the rest of us also have the freedom to call them out on it. The scientific method is a tool to reveal truth about reality. And no matter how much people believing in devine revelation want to claim otherwise, it is the only such tool humanity possess. People are free to ignore reality at their own peril. Turning science into an "-ism", is just a deflection aimed at destroying dialogue, it is an attempt at nullifying objectivity. If everything is an opinion, I have mine and you have yours, and all oppinions are equal, dialogue is impossible and the only thing left is tribal warfare.
