Actually if we are talking about science and not freedom of speech. Technically you are wrong, to work in science you have to follow scientific method and publish your conclusions with your methods, data and models.. etc. You can say whatever you want within this framework. A significant portion of the publications in any field is found wrong later sometimes by the authors themselves. But claiming that a work is fraud is not ab opinion. Actually even disagreeing between actual scientists usually comes in form of other work proving the other work is wrong. Welcome to the scientific community.
