Absolutely yes - Every country should deport those who are celebrating Hamas and what they did to innocent civilians in Israel.  

No one should get to stay in a country when they want to kill the citizens in that country for any reason.

There are a lot of Hamas lovers out defacing monuments and yelling "Death to America" in America - Every one of them need to go to GAZA and help Hamas do what they do if they love them so much - It won't take these ingrates long to want to come back to the USA.
