Totally agreed, but that doesn’t only apply to arabs, as I personally notice a lot of italians (for example) doing it (mixing english with italian), and for both the motives are different whether it is globalization, colonization or the famous sense of western and/or white supermacy.

Personally i only do code switching with other multi-linguals, but other than that it would only seem pretentious and not very polite.

No.

I speak english, italian and arabic. and it’s so much fun to switch between the three with other multi-linguals, personally sometimes i find it hard to switch to english after speaking italian for a long period of time, and when i read english text i tend to pronounce the numbers in italian as it feels much easier and makes more sense for me.

I think it’s overall a fun experience.
