This has been proven so many times.
But there is no better example of the hypocrisy of the left than California in the mid-70’s.
With the influx of Asians into California schools, following the end of the Vietnam war, the state Education Czar, Bill Honig, asked his “Expert” how best to assimilate these people.
As it turns out, this “Expert” was a rabid proponent of bi-lingual education for Mexicans.
However, in the case of the Asian immigrants, without any hesitation or hint of irony, he was adamant that FULL ENGLISH IMMERSION WAS THE ONLY REASONABLE SOLUTION.
Oh...did I mention....?
Jerry Brown was Governor then too!
