In California about 33,000 Chinese immigrants arrived last year. They out-paced the Mexicans, who sent in about 30,000. Arrivals from East India hit about 29,500.
And on average from 2010-2014 more than 250,000 Whites under the age of 20 alone - not counting anyone over 20 years of age, left California. I've lived in California - and I can tell you most of the fleeing Americans from California are NOT staunch defenders of Western Culture - so it isn't as if they are any use to the rest of us.
Western Culture is in full retreat in California - and elsewhere.
