Why is it that the only time you hear about white holidays/events are cases like KKK rallies?

I ask this because in my area, whites take pride in their heritage, being that most of them are of an anglo saxon or cajun heritage. Louisiana(especially Lafayette) is known for it’s cajun and creole heritage, and both groups embrace their cultures. Do whites in other cities have events for their ethnic origin(such as german, italian, irish)?

We have an Italian Pride festival where I live.
We also have cajun and creole events and festivals.
