Between 1820 and 1860 nearly 2 million Irish arrived in the United States -- 75 percent of them as a result of the potato famine. They arrived to an angry sneering American public who made proclaimations about how they would destroy the fabric of the nation and were regularly discriminated against. They have acclimated.
As a direct result of the onset of WWI, 250,000 German Jews came to the United States, adding to the 2 million who immigrated here from Russia, Austria-Hungary and Romania prior to 1924. They were looked down upon and worked and lived in the worst possible conditions. They worked hard and eventually they acclimated into society.
In 2010, 430,000 Asians (36% of all new immigrants) arrived in the United States. They represented the largest percentage of immigration (31 percent were Hispanic). Many of these people will be looked down upon. They will be ridiculed ... but they will acclimate into our society just as millions have done before them. And, we'll be a stronger country for it.
We aren't talking about every nation in the world sending their citizens to America and having us take care of them. We are talking about thousands of kids who are escaping with their lives and the clothes on their backs. We are talking about kids whose parents are still left to fend for themselves in places that are amonst the most violent on earth. You say we can't take care of them ... I say as Americans, we can't not take care of them. And one day, these kids will grow up to be a war heros, great teachers, scientists, police officers, preachers, and they will make their mark on a country who treated them with dignity and compassion. That is what this country is and that is what it ALWAYS has been.
