It is the very definition of being cis to not understand wanting to be a different gender than the one being assigned at birth. People who are uncomfortable with their assigned gender are not cis.
But many need a while to realize that other people do not feel the way they do.
Depends on what grapple means. Very few want to be a different gender than they were born, but practically everybody has been told to behave differently because "boys do X" or "girls do Y". People just want to do whatever their interests predispose them to do or express themselves in some specific way that society often deems wrong. So yeah I haven't ever really "wanted to be a girl" ever but a million times I wish people would leave me the fuck alone when they think I'm not being a man correctly.

This is what I mean by 'on a surface level.'
Oppositional sexism demands that those born in male bodies do masculine things, and those born in female bodies do feminine things. In other words it demands that everybody, not just those who are trans, conform to socially expected performances of gender.
However, cis people are afforded the security in feeling that their birth gender is the one that is 'correct' for them.
Cis people largely feel gender entitlement (projecting one's own perception of gender onto other people, and privileging those perceptions over the way others understand themselves), hence:
A lot of people don’t really care much about what their gender is
Trans people do not get this privilege. Trans people face the same oppositional sexism that cis people do (that all people that exhibit exceptional gender expressions do), as well as having to face cis people's gender entitlement being pushed onto them.
All this to say the joke is that the subject of the meme is in denial about their transness, and they are assuming that everybody feels the same way. The meme is a transfem centered meme- cis people may not get the joke; however many people DO care about their gender identity, but some identities are privileged over others.
There was nothing entitled about what I said. However you are minimizing the suffering that I and many others have gone through for not aligning to gender norms.
