Am I a bad guy? I don't think so

So some lady went on a tirade about me being racist for saying that it should be a requirement for foreign people who wish to live in the United States should learn English. each day I encounter people at my job who can't speak English at all not even broken English and even that in the work force slows everyone down.

Personally I don't have the time to keep bringing out my translator for temporary workers. and now I'm not saying they should forget their native tongue entirely but they need to learn enough for reasonable communication. any thoughts on this really I think that lady has no idea of what the word racist means my reasoning is very logical.
