I had a work colleague with your problem. In overseas travels he found himself subjected to harsher treatment. He gave up and anglicized his family name and changed to it by deed poll (new passport, drivers license, etc). Even though he retained his Arabic given name, the problems were much diminished. I know it is an extreme case, but it is an example of how desperate the situation can become.

Maybe it isn't as common these days, but in the 1950s and 1960s lots of Italian, Greek and other European immigrants anglicized their names to mitigate discrimination.

Of course, I am not suggesting that you need to follow those examples. But having an awareness of such extreme measures might give you ideas for changes somewhere along the spectrum.
