This may be controversial, but I think the US govt. should only celebrate and acknowledge official US holidays. Let individuals celebrate whatever they wish. I don't see foreign governments celebrating US holidays, and rightly so. I don't expect nor want the US govt to acknowledge Oktoberfest nor St. Nicholas Day nor any of the other "holidays" we celebrated in my family. So I don't expect nor do I want the US govt to acknowledge nor celebrate Cinco de Mayo, St. Patrick's Day nor Nowruz. I can think of better use for my tax payer dollars than funding another party celebration and decorations at the White House.
