CMV: "White people have no culture" is incorrect as a statement

Examples of potential white cultural phenomena (some might have roots somewhere else, but surely not all of them)

-Ballet

-Irish dance

-Opera

-Slavic, Finnish, Swedish mythologies

-Food cultures from any European country that's white

-Halloween

Of course these cultures are more specific than "White", but so are black people's cultures. Black people in Jamaica are completely different than African-American people from New York.

There might be a reason for people to say this, like self-empowerment or something else, and from an utilitarian perspective it might make sense. That does not make it correct as a statement though.

So when people use that statement they are usually reffering to white americans not white people across the globe. 

It’s usually in reference to white americans sometimes claiming a strong heritage/culture with their european ancestors despite not following anything of the culture. It is sometimes said in reference to USA being such a young (and big) country and thus its culture is nebulous compared to others. 

It is also sometimes said in opposite that “black culture” (reffering to black americans) is bad. 

But most importantly when people say it they do specfically mean white americans. Mostly this is a result of american discourse where often using white and black implicitly means white americans and black americans. So it goes.
