Protecting families and communities is basic humanity. It is every human right and a good deed to protect those that our vulnerable. This is a country of immigrants, some just came before than others. Don't discriminate. Think from your heart, with kindness and compassion. Nobody is saying don't make tighter borders but what will we get by separating immigrant families that are here already? Only heart ache, lots of socio-economic stress which leads to hatred amongst people. Terrorism is the result of human behavior and country policies that discriminate and marginalize people - be it poor or of the different religion, color or country. Think of the common good of mankind and keep that as a goal. Can there be any common good in hurting so many immigrant families?
