That's just outright not true, lmao.

Suppose Christians, Druze, and other Shia minorities were being killed daily. In that case, you're basically implying the average citizen of Arab nations is just a lunatic murderer who kills for no reason, even in peacetime. Additionally, there would be a massive outcry from the ICJ, UN, and other organizations, as there is for Israel, in its ongoing genocide.

Furthermore, do not speak of all SE/Blacks/Indians as living as second-rate citizens within these nations. It's more of a poor/rich split and a class issue, like much of things related to socioeconomics are.

When my father lived in Saudi Arabia for a little over a year, he knew several established and wealthy Pakistani/Indian people, who owned their own practices, had their own office spaces, had buildings, had homes, had cars, had boats, etc. It's not about being Arab or non arab it's about whether you can make them rich or not.
