Should We Let Them In?

This post is very controversial, As many people will probably disagree with me as agree.

Several things  about this current immigrant debate both amuse and concern me. So concerned  are we that persons coming from another country migrating to the US for a better life would cause damage such as kill us and destroy our homes, towns and cities.  Gee, that sounds like the history of our forefathers who came to this country and unmercifully killed and tried to animate the indigenous people who were already  living here. We  destroyed their homes and villages.  Sounds like ISIS in Paris last week and what we are afraid of in this country.
Should we have treated the Indians as we did? Why do we have the audacity to think it was okay for us as immigrants to destroy the lives of persons already living in this country, but look out for those dangerous Syrian immigrants.

Additionally, the talk of a Federal registry of persons in this country is scary. Are we in George Orwell's book? Does "Big Brother" need to kept better track of us? Isn't the census enough? I am not saying we don't have an issue in the world today, with the Taliban and ISIS, but we need to think about fairness and acting in a humane manner. What about the principles of our country?
