Why don't we have a Native American history month, or Hispanic? Is it because those races are just like white people, never have to face discrimination? Never have anyone judge them because of how they look?
Welp, guess you're right. There probably isn't a specific month-long celebration for every race, religion, culture, ethnicity, nationality, profession or identity on Earth.
Although California, at least (possibly other states, it's not worth my time to check), and Canada have Muslim appreciation/history months, and Jewish American Heritage month is in May, as is Asian Pacific American Heritage month.
