why did the west commit to multiculturalism?

[Philippus Flavius Homovallumus]

The sociological average of immigrant communities entering a host countries that applies across all groups is:

1) First generation NEVER loses their original tongue as a primary first language, and it is most usually the only language they speak in the home and with fellow community members.

2) Second generation is usually bilingual and often acts as translators for the first generation or grandparents or relatives.

3) Third generation has typically lost the original language and their strongest ties to the original culture of origin is food.

Except that the current "Second Generation" Muslims in Britain and elsewhere are less integrated and appreciative of their host country than their parents. They are reactionary, in many cases very deeply, in a few murderously.
