You mean you honestly have never heard someone use the term "A-rab" WHILE belittling Arabs? But yet you have heard people call them other names while doing so? Does this mean you've also never heard someone belittle Arabs while calling them "Arabs"?

I still think you're waiting for someone to show how the belittling happened in THE VERY USE of "A-rab" and THIS IS WHAT NO ONE WILL EVER BE ABLE TO CONVINCE YOU OF.
