No one can accuse the Irish of taking themselves too seriously. We excel at poking fun at ourselves and we do so with a soupcon of self-deprecating humor and wit. But as an Irish American who lived 19 years of my life in Ireland, I am truly offended by the way the U.S. celebrates St Patrick's Day and views Irish culture in general. It's insulting. Our national holiday is not about celebrating our country's supposed drinking culture; it celebrates our patron saint, the man who brought Christianity to Ireland.
