“A classmate told her the sticker was racist because many people can’t choose what they want to do because of structural racism.”
Better answer would be your classmate is a liar.
Structural racism starts in the ghetto with submissive misery.

There is a virtue in not listening to negativity. But it is sometimes years before that negativity is shaken off.
Your answer is correct, but I would add that everyone can choose what they want to do because we limit ourselves more than any outside force can. Don't be a victim.
Tell the classmate to move to Cuba or Africa and see how much better her chances are there.
