Probably because there is a, perceived or cultivated, associations between Muslims and immigrants/people of color. And if you can't outright punish someone based on "race" you go after the closest thing.
I understand your point and admit my comment could definitely be interpreted that way.
I could be a dick about it and demand people learn to pronounce it the way us Italians do, but then I'd also have to start pronouncing every English loan word perfectly and with a correct English accent while speaking Italian, and you can do that without sounding like a pretentious asshole, so I won't.
I use earphones to listen to music and take calls hads free quite often.
I recently got a new phone, a Fairphone 5, which doesn't have a headphone jack, and I'm already missing it.
Listening to music is fine, I just use a USB-C to jack adapter, but I've been told people can't hear me well when I'm doing the same to take a call.
The other day I was in the car with my brother for hours and wanted to put on some music. I couldn't connect to the car radio via Bluetooth because my brother already was and needed it to take calls and whatnot, so AUX cable here we go. Except apparently my phone does something weird like shutting down the USB port when not in use (reasonable) between songs, creating a noise like when you connect a jack to a powered on speaker, which was super annoying.
So, yes, I use the headphones jack and sorely miss it.
And, let me guess, you don't intend to quit
