You're also conflating unchangeable characteristics (such as skin color, or sexual orientation) and some feeling of group belonging. We would certainly find it a bit weird if someone felt that they "belonged" in a valued group merely due to, e.g. having light-colored skin, and expressed a need to "show off" that specific fact about themselves to others. That's key to the "identity" distinction PG is making here.

This feels like a false dichotomy: while you cannot change your sexual orientation, you can choose to make it more apparent and it has clear benefits for other lgbtq+ people around you (which, for me, gets it out of the selfish connotations of showing off: wherever you live, being openly gay still carries a non-zero physical risk, you don't do it just for the fun of it).
