It's xenophobic to exclude people who aren't from your country.
Lazlo is planning a big house party, and one of the people arriving is Nour, who is from Egypt.
Lazlo wants to party all night.
Lazlo greets Nour warmly and offers him a drink and shows him around.
Lazlo calls Nour a terrorist and says he can't come to the party.
Everyone has a great time, and the party lasts all night.
A bunch of people get mad and leave, and Lazlo's party dwindles to just a few people.
