I will be attending Bangor University from next week and I am also from Bangor. Born and raised and my whole family lives here. I can assure you that we are definitely not racist or islamaphobic. There are many people with different cultures, religions, backgrounds that live here and study here.
Of course you may come across the odd one ignorant human being as you would in any part of the World but in no means is the city racist, islamaphobic or any hatred as a majority. As a local and student if I ever was to witness such behaviour I would certainly step in and say something and do the right thing and I would like to think my fellow locals and students would do the same.
At the age of 26, I can honestly say I have never witnessed such behaviour, not saying it doesn't happen but just trying to put into perspective how little it may happen
