DEFINITION
Gender Apathetic (also known as inersgender, anvisgender, or apagender) describes those who are apathetic towards their gender identity and do not care what gender they come across as. It is different from agender in that one may have a gender and/or feel gendered, but it's unimportant what that gender is or whether it's even there at all. One might use labels such as trans apathetic, non-binary apathetic, cis apathetic, etc; however, this would just be what the individual leans towards, and it isn't neccesary for one to use these terms. One might say "I don't really think about it, but I guess I'm..." to those who ask about their gender.
Gender apathy may be confused with cassgender, which is when someone feels their gender is unimportant. The difference between inersgender and cassgender is that inersgender individuals don't care how others gender them, whereas cassgender individuals may still feel that how others address them is important.
It could potentially be included in some cases in the international non-binary day or the agender awareness day, but there is no official day for inersgender.
