In confusion
Now, we do not really know all the new genders that have emerged in recent years, there is a lot to remember. Out here we believe in just simply treating people with respect and showing them kindness wherever we go. So far that strategy has worked out fine, so we see no problems yet.
This person jumped to conclusions about the new gender terms without knowing the basic information about them. A cisgender person is a person who identifies with the sex they were assigned at birth. So the first commentator clearly jumped the gun and took aim at themselves with this nasty online post.
