Without trying to detract from your experience, I would suggest that your experience as a Black person in Bangladesh, India, or China would have been a whole lot worse. Heck, even though most Muslims aren’t Arab, it’s pretty darn clear that the Arabs think that is south Asians are second class citizens in the Muslim world. And unlike white southerners they’re not passive aggressive about it.
Without trying to distract from your suggestions, I would like to state that I have never seen race segregated mosques anywhere in India, while these seem to be widespread in the United states.
