certainly...I'll try.
STEM stands for Science Technology Engineering and Math....ya know..the useful stuff? The kinda thing that digs a hole in the ground, lays pipe, and provides clean water?

Everything else is a hobby by comparison...like writing essays on the evils of this or that...instead of DOING something about it.

Making movies about this or that...instead of DOING something>
newspapers, journalism, pyschology, sociology, woman's studies, gender studies, etc, etc, etc...instead of DOING something about it....

does that help?
