Although society may be moving in the right direction of becoming more understanding and accepting of those who don't fall under the cisgender umbrella, associated with being cisgender.
People who are queer face more discrimination throughout their lives than people who are heterosexual do.
But gender identity is a more expansive view that goes beyond your sex.

For example, some drag artists who think of themselves as cisgender go on.
That said, it is a choice for each person what labels they are comfortable with using for themself, and they may find other ways to label their gender.
For example, a male who is cisgender will identify as a man, and a female who is cisgender will identify as a woman.
