Reality time here.
In 19th century America and into the twentieth as well, an even more white, Anglo-Saxon Protestant mind-set prevailed across the United States. From the so-called Know-Nothing Party adherents in th 1840's, through the Civil War, to the anti-Irish (and Catholic) riots and discriminatory hiring practices through the Klu Klux Klan to the draconian restrictions on immigration enacted in the 1920's during the heart of the 'Red Scare' and on into the present day's anti-immigrant mind-set, America's general culture has not always been not as accepting of foreigners who spoke a funny language, wore odd clothes and even worse, practiced a religion that no one had ever really heard of as our popular mythology would suggest.
The first Orthodox immigrants to these shores had other priorities on their plates than evangelism. They had to learn a new language, find and hold onto a job or jobs, band together with their fellow countrymen and co-religionists and acquire land, find a priest and build a church building, marry, raise a family in the Faith and in the traditions of their ancestors and most importantly, obtain precious citizenship.
Many faced ridicule and humiliation on a daily basis as they tried to live their lives. For those who were Greek Catholic, they found themselves surrounded by both the general Protestant establishment and a Roman Catholic Church that refused to acknowledge their right to exist and which tried to thwart them at every opportunity. For both Orthodox and Greek Catholics alike, many worked to the bone, sacrificed much to establish their beloved churches, only to see them taken away through schism, overseas revolutions and the very evangelism that you speak of by the Protestants as a final insult to their dignity.
Frankly, I have to say this. The very asking of this question in the manner in which the OP posed it points to the heart of the reasons why many of us who were born into Orthodoxy and are the children and grandchildren of those who planted the faith on this continent have a problem with the attitudes that many converts bring with them as they discover the beauty and saving grace of the Orthodox Faith.
Now that the Faith is planted and maturing, we all have to work together to move past these man-made divisions within our parish communities and across our jurisdictional lines. If we fail to do so in a charitable and loving manner, the next question posed in the future will be how did the Orthodox allow the Faith to die off in North America.
