In a just world, you’d have been bumped up a grade, moved into an advanced track, or given time in advanced sessions with other gifted students. That said, your teacher would have been responsible for making those recommendations.
Oh that did end up happening eventually. I did go down that track. Ended up taking calculus freshman year of high school.
Your point three really hits hard. It's amazing how often respect, even among allies, can be contingent. Among some folks, do something they don't like? They'll weaponize your birth sex against you. You can see this tendency in response to news stories. Trans people are just like any other group - there's saints and sinners among us. Some of any group end up being sociopaths who do terrible things. When a trans woman does something legitimately horrible, you'll see even allies aggressively misgendering them. When I see that, it's a clear reminder that they don't truly view trans identities as legitimate. They respect or humor your identity based on politeness, but they truly don't view it as real. No one starts calling a cis woman a man when they commit some horrible crime. A cis woman could literally rape and murder children - she still wouldn't be called a man. She would be called a monster, but her gender would not be stripped from her. The same is not true for trans women.
But yeah, in normal social interactions, I absolutely get the lack of aggression. I consistently feel the need to be less assertive and aggressive than cis women.
