My grandfather was deported (three times) during Operation Wetback. He was a permenant resident. His family were Tejanos before Texas was annexed.
They took him and his brother when they were just boys. He told me around 11/12 years old. INS just grabbed them put them on a bus with a whole bunch of other hispanics and dumped them across the border. It took him and his brother (keep in mind they are just kids) about a month to get back across the border. When they made it back their parents were gone, along with their sibilings. My grandpa never saw his parent's again. He doesn't know where they were taken. Since they were just kids, with no where to go, they were rounded up again and this time, like Trump said, they were dumped farther South.
They spent a few years working their way through Mexico and re-entered through California. Miraciously (my grandpa always labeled this a miracle) , he found out his seven year old sister not been deported and had been placed in a foster home in California. He tracked her down and when he tried to re-unite with her he realized she was more put into indentured servitude. A lot of the small kids were. After a few years of literally battling (having shoot outs) the people that had her he was able to get her back. [She is currently suffering through Alzheimer's and apparently re-living alot of what happended to her during that time.] My grandfather, after getting his sister tried to get them back to Texas, but they were promptly picked up and deported again.
This time, my grandfather was seperated from his brother. It took him almost 20 years to find him again and when he did, his brother was a homeless wandering Texas/Mexico bordertowns. He was a drunk and addicted to drugs. Growing up, each year my grandfather would drive from Juarez to Reynosa looking for his brother to give him shoes and winter clothes. My grandma refused to let us go with him.
That program and the deportations in the 1920/1030's were just as racist and fucked up as the internment camps of WWII. I can't help but taking a little bit personal when Trump advocates for that shit. No asshole, not everyone likes Ike.
