Of all the things in the world to be upset and offended by. Sad for you but pathetic for them. Yeah, maybe weak minded or insecure along with narrow-minded and perhaps judgmental.

Some people really do not understand how someone can be a different gender than the anatomically assigned one or can be both male and female genders. However, they can often come to have some acceptance and understanding with more information or personal contact rather than it just being an unfamiliar, abstract, and maybe even absurd idea.
