What makes you think those traditions are threatened? Immigrants bring their traditions and increase the diversity of traditions and cultures in a country (they don't replace them). Americans love Mexican food - burritos and tacos didn't replace our hot dogs, burgers and southern fried chicken. We celebrate Christmas AND Cinco de Mayo! How boring would it be not to have Chinese, Indian, and other ethnic restaurants. I love Italian food, but not every day of the week. Don't believe the fearmongers telling you your traditions will cease to exist because of immigration.
