You read too much into my comments. The particular cite I wrote in the movie is about the white intelligent couple and their ‘counterparts’ in the movie - who happened to be white, also. So your assumption that I was speaking of non-whites is wrong.
Further, I commented on influx of immigrants, both legal and illegal being a detriment. Please show me where I used the comment ‘non-white’....
Your inaccurate linking of my comments to your referenced study is rather a stretch if you ask me.
