With no disrespect intended, I think that this thread shows a very egocentric viewpoint. It is not just the “heimish” who are abusing English – it is more or less every immigrant group in America – which is a lot of different groups of people in this country! The Russians, who never seem to use articles in their speech (since Russian has no articles), the Hispanics with their frequent lapses into Spanish, the Jedi with their Yodaesque reversal of subject and predicate. Every group seems to retain some of their “native speak”.
And there is little discouragement here. We try our best to understand everyone who tries to speak to us in English and overlook their mistakes. Not so in other places – have you ever tried to stammer your way onto a bus in Israel? You’re likely to feel humiliated if your Ivrit isn’t perfect. Ever tried to speak French in Paris without the perfect accent? You’ll be completely snubbed. In fact, I can’t think of another country that is so forgiving to non-native speakers. So let’s try to see it that way.
