Race is a construct made by society to group people with similar physical characteristics, ethnicities, and/or shared experiences into defining boxes

While race isn't determined by biology, there can be similar biological features that are similar among people of the same race, like
for example melanin presence. Biology has been used in the past to defend racism, like for example there was a study in the past that said Black people had smaller brains and a higher pain tolerance. While these studies were disproved, their consequences still have effects in modern day.

A belief held that white is the superior race, and that white people should be treated better than the other races and can look down on the other races. Some examples of groups that have this belief is the KKK and Nazis

People of the same ethnicity are commonly grouped together in the same race, but not exclusively. For example, people from Kenya would likely all be considered Black

Antiracism means that you are actively working to combat racism by understanding injustice better and putting in a lot of effort to work towards racism, whereas not being racist just means you aren't racist.
Not being racist doesn't make progress, while antiracism does. It is super important to be antiracist.
