This is good PR while at the same time a rebuke to the Trump administration. The key, of course, is not just the sign but acceptance of foreigners when they arrive. The xenophobia demonstrated by the government is not the way the country was built in spite of past exclusion laws. We know what Hispanics bring to the country. They have added food, culture and hard work to the American mix. We might not understand yet what Arabs and Muslims will bring but if we deign to look, we can surmise what a large population would add to our neighborhoods. If history remains true, each new ethnic group has given more to the United States than it has taken from the government and its citizens. These signs are testimony to that fact and are more accurate than the administration’s attitude.
