Scarred or scared?
In any case, I'm one of those "$&^&%1 [insert curse word of choice] converts" who sees absolutely no point in sticking someone coming to Orthodoxy into a parish where services are primarily in another language, IF there are English-language parishes within a reasonable drive.
Someone coming to Orthodoxy has enough to deal with, without throwing up a language barrier.
If someone has a talent for languages or is interested in Greek culture, that's a different case, but that's not the situation many inquirers are in.
Illustrative example: your normal American guy inquirer, someone I know, had been attending a GOA parish for some months. He went as he really liked the priest. However, he was isolated in the parish, people never spoke with him at coffee hour, he sat in a corner by himself - he's not Greek. He tried to get his family to come to church, but after 1-2 services (almost totally in Greek), they refused to attend anymore. He's now attending an an English-language parish and the kids are *asking* to attend church (wife still hasn't come around due to bad experience with the language issue at the GOA parish).
