Oh, please, it's you who needs to "get with the times". It's 2016, not 1974.

It isn't about skin colour, or "reproducing the traditional ethnic makeup of the country", it is about:

1. How much mass immigration in a short period of time is "digestible" in terms of successful integration, both economic and social, particularly when immigrants cluster in a small number of urban areas

2. A small but  identifiable segment of that mass immigration that hold values antithetical to basic Canadian values, and create enough controversy about it that it has become an issue for many Canadians
