I thought it'd already become a common alternative of Anthony in English areas. It'd even got a standard English pronunciation. So I see it as a part of history and culture. You can't say another language is trashy just because people in the ghetto speak it. Their motherlands were colonized. Hating the poor is not a virtue.
As a native Frenchman, I can say that this is a perfectly lovely name. It's such a shame that Americans think of it as an exclusively black name. It's even worse to see it butchered into spellings like Antwan, Antwon, or Antawn. I know lots of Antoines, both white and black. No one here regards Antoine as trashy. (On the contrary, Anthony is considered a bit trashy in France, since it's an English form of a name that already has a common French form, and most anglophones wouldn't consider Anthony trashy.)
