If you identify as gender-fluid because you possess qualities normally attributed to neither/both genders, aren't you just confirming your belief in gender stereotypes?

For instance, I'm a gay male whose favorite color has always been hot pink. I've never felt the desire to wear a dress or anything like that outside of drag parties but, if I did, I would still identify as a man. Just a man wearing a hot pink dress because it's comfortable or whatever and that's my favorite color. If you think that cross dressing or behavior atypical of your gender necessitates your adoption of a new gender, aren't you making a statement that men shouldn't wear dresses or women shouldn't play sports /date other women?

DISCLAIMER: I'm posting this here because it's a thought that I had in the shower, but it could also be suitable for r/changemyview; I'm actually curious. I am also not making any kind of point about transsexual people. I understand their stress about being born in the wrong body and the idea of conforming to a gender with which you are more comfortable. My confusion comes from those who switch back and forth seemingly based on convenience and stereotype.
