Well I look white but am about 8% Middle Eastern , guess that makes me some sort of mongrel by your interpretation , but I really do not care , got two children who are half Asian and grandchildren that are Maori/Filipino/English.
Not sure how you are going to "push back the invaders"
Suspect part of the reason there is lower birth rates with Europeans is they are more self centered than other cultures that are more into being family orientated , I notice that with the Maori side of our family who are always having family gatherings ,
