Funny enough, you would probably categorize me as a "STEMlord" if you knew me in person. In general I try to keep these types of communications as straight-forward as possible online. Many non-productive discussions that I have seen online originated from statements meant to impose heavy implication. These kinds of statements are generally taken worse with the lack verbal communication and body language. From what I have seen, it is generally better to give these faceless discussions some effort up front to ensure level footing for both people.
PS: I do believe humanity needs professions outside Science, Technology, Engineering, and Mathematics.
Research related to National Defense are usually kept confidential, and corporations have an incentive to not share there research to maintain competitive with their competitors. Neither of these seem out of the ordinary regardless of where you are on the globe.
Even still. The US government funds various institutions that share their research publicly, so I am not sure where you are really going with this.
