You're right, it's not a good reason. I'm just skeptical how social sciences can come to fair conclusions when is almost no representation of the political right in their field. However you might be able to say the same about tech CEOs and underrepresented female gender, so I don't have a good argument here. As an aside I feel much less comfortable arguing this point after checking out your personal site and seeing that you write Debian packages. I really enjoy Debian, especially the reproducible builds work that's going on over there. I respect your opinions on this matter.
