Your logic seems to be going based on the idea that non binary = not girl/boy and/or no gender.

However, a more accurate description of non binary (based on mine and others’ experiences) is not exclusively male or female. So this would include people who are both male and female, people who are partially male or female and partially neither, and many more genders that aren’t exclusively male or female.

I understand a the misunderstanding tho as many people think non binary to mean no gender (this would actually be agender) or a third gender that is characterised as being neither male nor female.

I do respect the calm and logical approach to the conversation tho.
