it is in no way racist to expect an immigrant to speak the most common language here in the US.
If they choose not to they put themselves at a big disadvantage.
If you choose to move to France, learning French would be expected.
BTW, I only know a few sentences in French, but when spoken politely, have found the French people
to be very warm and kind.
The words are.
Excuse me, :: excusez-moi
I do not speak French. :: Je ne parle pas français
Do you speak English? :: Parlez-vous anglais ?
