Some people think that if Syrian Refugees come to the US. They think that ISIS will come after the united states. ISIS might also come in as "Syrian Refugee" and attack. The US doesn't want to take the chances of that happening. Some might also think there fine and that they can help themselves. Others who don't like the Syrian Refugees might think that they might just be working for ISIS or blending in. They might think or see a different side of the Syrian refugees then we do.
Rebuttal
Even though the Syrian Refugees have some bad traits we believe that the Syrian refugees good traits over power the bad traits. They are just people trying to fight for their lives. They did nothing wrong. They should be let into the US because it isn't their fault that ISIS exists. Most of these traits are not even a benefit to them they are lost and are being pulled in all the wrong directions. They wouldn't want ISIS to enter the US and believe me they would fight back.
