I don't see this as intrusive as such, I follow people based on interest. So if you're posting on Physics, Chemistry, Astronomy or some other science based topic then the subject matter is an important key factor,
Also bare in mind, following @nasa or @spacetelescope
foir example you are following organisations that are diverse, but they are more than 1 person so organisations don't generally have pronouns.
I think scripts such as this could be useful for personal research in to how many people from a particular group post about subjects but again, how scientific or accurate is that.
I don't think you will be judged based on your follow list.
