From this announcement:
Applications for the Yiannopoulos Privilege Grant, a college tuition grant created by Breitbart News Senior Editor MILO exclusively for white men, are now being accepted.
Yiannopoulos explains the justification for the grant in the announcement by saying (emphasis mine):
“It started as a joke, but if you’re a women (sic), or you’re black… If you’re disabled, or you’re Muslim, or a refugee… If you identify as an attack helicopter, you can get free money,” he continued. “But the facts say that actually it is young white boys who are educationally underprivileged. As educationally underprivileged as many other groups..."
No evidence is provided for the bolded claim. What "facts" are Yiannopoulos referring to?
