Can someone explain to me the need to be represented?

Just my opinion, and why I wish I saw more well known LGBTQ+ physicists and engineers.

Just like with everything else, as long as they are the best person for the job and not given the position over someone who is more qualified, but really, why does it matter? Maybe I'm too jaded, since I know based on representation in the field that skinny, pale shutins such as myself have a lot of clout in STEM fields.
