People will rarely reproduce with people who look drastically different than themselves, the myth about people prefering interracial partners instead of intraracial ones is perpetuated by the disillusioned media. Whites will most likely reproduce with other whites, as such there will not be a lessening of white genes. Media and real life is so different, and interracial couples are shown to be more normal than in real life. Meanwhile sociology proffesors are babbling about the average european being mixed race, is nothing but pure bs. You need not worry. The only thing multiculturalism will bring is segregation and possible civil war. Multiculturalism is not a new experiment, but one who always fails.
