Azor: I don't understand the term pro science.
While we sometimes use the word "science" in connection with a particular field of study (biology, chemistry or physics, for example), it really is a philosophical world view.
Note this definition: Science - the intellectual and practical activity encompassing the systematic study of the structure and behavior of the physical and natural world through observation and experiment.
Science is a system or approach for acquiring knowledge.
As such, a person could most definitely be for or against this particular approach to knowledge and understanding. It certainly undermines any person or group claiming to have revealed knowledge and to be the sole possessors of it.
This explains why the GB of JWs, for example, are anti-science, although not explicitly. Their anti-science stance is subtle, but it is definitely firmly entrenched in their "theology," doctrines, policies and practices.
