I'm a white guy but I HATE white supremacy and everything it stands for

As a white guy I'm ashamed to see to what extent the farmland is infested with supremacists, it makes me ashamed of being a white guy and I realize now white people can be just as prejudice as people from other races (I'm not saying that people from other races are prejudice) and I wanna do something to make this prevalence of hate go down do you have any ideas on what I can do, it's my birthday today but seeing all these racist, bigoted people on this site and other online platforms makes me feel ashamed of my skin color and it makes me feel terrible.
