CMV: Gender identity is a useless construct that appropriates the actual mental illness gender dysphoria.

In my view, gender identity is identifying with a characteristic that doesn't describe you, like identifying as tall when you're a short person, or identifying 20 when you're actually 60. There are people with actual gender dysphoria which is similar to body dysmorphia and it is a serious condition that currently is best treated by transitioning, in that case identifying as another gender is a therapeutic tool and the only solution to the mental illness. When people claim to be trans or nonbinary or any other type of non-cisgender without the diagnosis of gender dysphoria, it appropriates a mental illness and is basically the same as someone claiming to have OCD, depression, anxiety, ETC... without actually having them.

EDIT: my view has changed I understand the other side and thanks to you guys see gender identity as a spectrum. Thank you guys.

To change your view on this, it might be helpful to think about gender dysphoria as a spectrum rather than a binary (yes/no) kind of thing.

For example, I've known people who have a gender identity that doesn't match their biological sex that experience milder forms of gender dysphoria.

It's not intense enough to require therapy or a formal diagnosis (which is expensive for many to get). Rather, a few lifestyle factors can be changed to mostly manage it. Gender transition isn't absolutely necessary either (and indeed, for people who are non-binary, transitioning wouldn't help things).
