I agree with you 100%. With major tragedies there will always be holes in the story which will inevitably be filled with hypothetical beliefs/theories. Whom ever makes the claim needs to defend the claim. Pointing out inconsistencies in a story and expressing skepticism is not the same as making a claim such as: "George Bush and the Reptilian's did it."
