I'd vote for it (note: I'm not white). But in this day of age anything pro-white is considered racist. In other ways black history month and Hispanic month are there too remember the influence certain minority people had in this country and to celebrate those groups. In my opinion maybe it's best to get rid of those remembering months and choose one month out of the whole year to celebrate all backgrounds and ethnicities in the U.S (including white people) and remember all those individuals that played a role in forming the country that is The United States of America today.
The call for recognition of the contributions of minorities in the United States is likely due to the emphasis on european (white) history in the founding of the country. It is to provide balance and richness to the curriculum, and to help us all to understand the many threads that have been woven into the seamless fabric of the nation. When you take a history class in elementary or secondary schools, the figures in it are likely European, so the recognition of other threads happens in that context.
