Every where there is discrimination even in so called heaven and even in my and your home. There is no 100% equal treatment.
We may have mistreated them but for sure human becomes bias on following grounds: Race, Religion, Nation, grid, Language, minority, elite caste, wealthiness, Educated with less wisdom and logical thoughts and so forth.
So, no matter how long they have been in the country they have been residing if they were not born or raised their childhood in that country will not feel part of the nation and some time they themselves create discrimination situation. 
Mexicans living in USA for over 20 years do not learn English and they want to be spoken in their native language and argue about discrimination.
So, did in NPR news, people from Muslim countries wanted to be recognized from their culture and religion rather than people individual and blame others being discriminated. If someone wanted to be communal than individual recognition then he/she will be different and there will be some or more discrimination.

i So the bottom line is how we going to look at a glass of water half empty or half full.
