Don’t worry, they speak Arabic because Arabic is the language of the Quran, and they still must keep their lineage intact even if they are in another country, they want to continue experiencing their identity, and not lose themself. There is no need to feel disturbed and I appreciate you sharing your perspective, but I assure you there is no need to worry, and as we all know, people have many different personalities, some are good and some are bad, if you see one Syrian who is mean to you, or judges you, know that one person or a few doesnt mean the entire nationality is like that! There are good and bad people everywhere! But yeah I too, wish them happiness when they return. I love Turkey as well because I’ve seen what most people I know who are Turkish are like, and love both Turkey and Syria!
