Does equality as a value fundamentally contradict individual rights?

This is something that I’ve been having trouble reconciling.

If a child has a packet of Haribos, and he chooses to share that with all his classmates, except let’s say the Italian kids in particular, I think everyone here would agree that this kid is racist, right?

But isn’t it technically true that this kid has absolute sovereignty over whether he shares the Haribos with any person in particular? Like, if he wants to offer the Haribos to his classmates, is he now ethically obligated to share that equally with everyone? Or not share anything with anyone at all?

Did this kid commit the wrong when he refused to share with the Italian kids, or when he chose to share in the first place?

Like in general, from the point of view of someone trying to get a “yes” from others (for anything that is within the jurisdiction of “others”), it’s pretty obvious that equality is paramount. But from the point of view of someone deciding whether to say no to others, does it not also seem pretty important to be able to choose who to say no to as well?
