I've encountered this viewpoint before and it took me a while understand the nuance of the assertion - as it is so matter of fact it is easy to take "not a science" as a value judgement - especially as we often enshrine empirical thinking. As with all things though, it comes down to definitions and with the more specific and academic understanding of science, it is easy to see how (pure) mathematics isn't a science. Indeed, a lot of computer science somewhat doesn't fit well as a science - like FP. It's quite a controversial statement that can be construed as aggressive which is probably why you're getting downvotes but I think you're right to point out how confronting your own assumptions/axioms can bring out strange reactions.
