Your average Chinese, or Hindu is going to give you a similar answer.
For a Mexican raised in the USA, a visit to his own home country of Mexico is simply not going to seem very different at all.
I disagree completely. A large number of young children were brought to the US in their infancy, have no experience of Mexico at all, no remaining relations in Mexico, and speak almost exclusively English.
Skin color is utterly meaningless in this debate, for example taking a white American high school student and putting them in Russia, with a hearty, you’ll be fine, Russians are white people, too. They would be utterly lost, and would fall prey to the first villain they encountered.
Add to this that many families are mixed, with some illegal and some US citizens. I have known several such families, where grandparents, parents and children are illegal or legal with no rhyme or reason. Often citizens know minimal English, were educated or not in Mexico, and are entirely “old world”, where their illegal grandchildren speak English fluently, attended school in the US, and are wholly integrated.
It would be incredibly cruel to deport integrated people to what for them is a foreign country, splitting up families, taking children away from their parents and vice versa. There has to be a better way.
