Gender
Gender is complicated. That's something we're beginning to realize. At first, we thought it was only a boy or girl. But now we have transgenderism and nonbinary in the mix, not to mention unisex. However, this isn't some new phenomena that's suddenly taking form in the last decade or so. This has been going back since the start of human civilization. Are you familiar with the story of the goddess Ishtar's descent through the underworld and how Ea, the god of wisdom, created an androgynous being named Asu-shu-namir to save her? If not, I suggest reading up on it. It's pretty interesting.
To define gender isn't as straight forward as one would believe. Normally, we would identify gender based on reproductive organs. However, I believe that gender is defined by how one feels about themselves. But even then, I'm not a hundred percent sure if that's accurate. Perhaps there really is no true definition of gender. I'm not entirely sure, but then again, perhaps it's really none of my business. If one identifies as man, woman, or nonbinary, then so be it. It is not my place to judge, nor my concern. As long as they're happy with themselves that's all that matters.
Unfortunately, there are always going to be those who don't understand or refuse to understand that demoralizes people who are different. These people use their governmental positions and their church sermons to decry and shame those that don't identify with their sense of 'the norm'. If you're one who identifies that there are only two genders, I understand your position, but unfortunately, it's not that simple. And to remain ignorant of that fact is sad. If you're the kind of person that believes that transgenderism is the result of some sort of physiological or psychological reasoning, that sort of thinking is what demonized innocent people for trying to be comfortable for who they are. Keep in mind that we believed (and some still believe) the same thing about homosexuality and the idea to "fix" them was conversion therapy, which led to many LGBT+ people getting abused both physically and psychologically.
The bottom line is whatever you identify as learn to love yourself and don't be cruel to others about it. And for everyone else show some compassion and humanity.
The world is ever changing and evolving. Time to evolve with it.
