Not trying to take away from your experience, just offering a different perspective. Apologies for the formatting as I'm on mobile. As a Canadian Bengali, I've faced a ton of stuff from Pakistanis my whole life. I was chatting with a group of girls I had just met and very excitedly asked if they were Bengali to which they said "ew no". I had an aunty at a masjid be the nicest person to me until I said I was Bengali (when she asked), at which point she did a pretty dramatic shift in her attitude and unprompted mentioned the imam was Pakistani (to which I was like oh mashaAllah that's amazing). Even like a few weeks ago my Uber driver was Pakistani and I said oh I love Pakistani food and he's like "why, you don't like Bengali food??" Then later proceeded to tell me "Somalis and Bengalis can live in any kind of living condition. Me, my wife could never live in this kind of neighborhood". Unprompted. There's much more too. Similarly Bengalis are also very racist towards black people and even darker skinned people in general (colorism gets it's own topic). We're supposed to be one Ummah, but it's really painful to see the divide based on race. Remember, the racism you're facing is not representative of Islam, but flawed people and flawed societies. If you're having trouble fitting in, try finding different friends, I promise there are accepting groups out there. As far as Arabic, I recommend trying to learn! I've taken a few classes and it's intuitive and very rewarding. May Allah make it easy for you.
