As for culture, children learn what they are shown and taught. If you expose your children to your cultural beliefs and the beliefs of other cultures, they will accept and know of them and make sensible decisions for their own lives. In my two religion and bi-racial home, we celebrate all holidays and have items of many cultures. In December, my daughter enjoys sharing in celebrations of Hanakuh, Kwanzaa and Christmas. Other times of the year allow for other celebrations, recognitions and always lots of learning and sharing.
People speak their minds.
It is their American right. I merely ask why they speak of race contamination, impurity and spew words filled with misunderstanding, mistrust and vulgarity. Instead, they should be striving to learn about their own culture and what their culture shares with others. We have different cultural backgrounds, different skin colors and different religions. Together we can make the world a wonderful place and fill it with unique colors and personalities.
