Diversity may be a positive thing in some ways, but the US has thrived and functioned as a country because of its immigrants assimilating and assuming American ways, writes Jonah Goldberg in the Los Angeles Times. However, a strange trend has emerged in liberal circles that seeks to demonize integration and the creation of a melting pot. Too much diversity, in terms of people that don’t integrate enthusiastically, can be bad for a country. Shared values, customs and institutions are crucial so that a nation may function successfully. Immigration is not the issue, but it must always be combined with a strong drive to assimilate and fit in.
