Absolutely, but the difference is that no one church is dominant in the United States. Even if we were to claim that Catholicism (the largest faction, although not a majority by any means) were the dominant one, within that church there is also a lot of diversity of thought. As an adult, you can realistically pick and choose with whom to associate at these churches, unlike say Twitter or Facebook where are beholden to whatever religion they follow.
Social spaces are all vulnerable to the weaknesses of humanity. While I do think the mechanics of the medium play a role in how those weaknesses surface, the source is and will always be us.
