Actually, no. And I used to live near there. All the orthodox I met spoke hebrew.
Yiddish is associated with essentially ALL Ashkenazi jews, of whom a huge proportion emigrated to the states in the 19C and there later achieved an over-represented awareness in the wider culture due to their high concentrations in geographical areas which were over-represented in mass-media, starting with theatre, then movies, then tv. As such, many if not most americanised people associate jewry with yiddish, although this is fading as mass-media has moved away from its previously (eg, 20s-50s) intensely geographically centralised sources.
Oi vey.
Get it right, already.
