Islamophobia is a real problem in the world today. It is not unrealistic though because when a person looks and talks the same as a terrorist does, of course you have to be careful. But, not all who look and talk like a terrorist are terrorists. So, what can be done? Education is the key.
The more you know about the customs and the fact that terrorists are extremists, the more you can realize that most Islam people are good...only some are threats. You can research into the people, the country, the customs, and the religion and find out things that will help you be more at ease with those who are Islamic but are not extreme like the terrorists are. Yes, education and awareness are tools which can help bridge the gap so the innocent Islamic people are not treated unfairly.
