That is a fond idea many people got that as long as you say that this is science you can talk any nonsense and get away with it.
Not surprisingly, you got that 180 degrees backwards.
If someone says something is scientific, there is a well-established set of criteria to assess the accuracy of the statement, and a large contingent of people well-versed in science to test it. On the other hand, if someone says something is religious, or spiritual, or new age, or alternative, or any of a host of other ill-defined mush-brained concepts, there's no real way to evaluate the truth of what they say within those "disciplines" because none of them have any method for determining the accuracy of their claims.
