coming up with a new kind of Gender Theory where if you've ever considered what your gender is and how it informs your personal identity and presentation, then congrats you're deemed as having a capital "G" Gender. you can be trans and have a Gender, you can be cis and have a Gender. you can be non-binary and have a Gender.
being a gender or sexual minority predisposes you to the ability to have a Gender, but doesn't automatically grant you one. note how many white cis women bemoan the existence of trans men as failed lesbians or whatever. the key part of my Gender Theory is the "personal" part of it. it's about how you relate to yourself, not how you relate to our gender biased society at large. anyone can have a gender, but you need some introspection to have a Gender.
the most important outcome of having a Gender is me deciding whether i can respect your opinion about video games.
