Sect really doesn't matter. Your objection is that the exchange is Un-Islamic. However, here, you make it about the exchange not following your particular sect of Islam.


Don't make foolish assumptions. Not every Muslim has an Arab name. There are people with Arab names like Usama who are not Muslim. Maybe he converted some time later during his life. Judging by your gross arrogance/ignorance about this matter, I sense that you may be a Muslim of the Arab nationalist variety, probably of the Salafist/Wahabbi school of thought. I won't make assumptions though, so that's merely a guess. You should specify which sect you are expecting the exchange to be.

Your other points are quite relevant though. There can never be such a thing as an "Islamic bank" or "Islamic exchange", because capitalism is Un-Islamic by its predatory nature.
