One of our clients (from syria, before the war started) was *very* islamophobic and kept slagging off muslims, he also saw a news item about nick griffin on question time and when i went in to work one day started asking me about him and telling me he thought he was right (this wasnt in the UK and it it was about 5 years ago)
You need to be prepared for things like that. Someone whose fled a warzone or any other sort of persecution isnt going to necessarily have tolerant views, they're not gonna be the easiest person to be with a lot of the time (as you wouldnt be) and may have pre existing MH issues that were there before the war. There are people fleeing syria who are islamophobic, there are people there who support bashar al assad and fled rebel-held regions, people who are gonna have views you strongly disagree with. There are also gonna be people who have serious drug and alcohol problems, anger management issues etc or just someone who may be very pushy and always demanding stuff etc - just like in the uk. You need to be patient but you also need to be aware that they might be difficult or even someone that you wouldn't 'like'
I am not trying to put you off btw! Just letting you know what issues you could face. Good luck
