The fact that this article offends left-wingers so much by simply mentioning demographic change (i.e. population replacement of Europeans) shows exactly why it was so badly needed. If China can be predominantly Chinese and Nigeria can be predominantly Nigerian, why can't Europe and the U.S. - which was built up by Europeans - be predominantly European? Doesn't mean no newcomers are welcome, that would be an absurd position. But a conservative immigration policy does mean prudence both in terms of numbers and in terms of the choice of which newcomers to allow in, as newcomers with more similar cultural backgrounds simply blend in more easily. If we don't do this, what our ancestors have built up is at risk of being washed away, and this is what we're seeing across the West these days.
Oh well. Nigeria has over 250 ethnic groups and the largest one (Hausa) barely forms 30% of the population. Sectional conflicts and strifes are a constant in the history of the country. You think that's more homogeneous than your average European country? Lol.
