There are forms of Christianity that is not as openly harmful to others. I am not suggesting any of them, though, as they are all essentially patriarchal. Unitarians tend to be on the low on harm to others scale, though. Evangelicals, particularly Calvinists, seem to me to be pure evil.

Conservative Catholics, on the other hand, simply seem to want those "good old times" high middle ages, and to party like it's 1199 again... Curiously there are also things like Catholic workers, which is a modern kind of socialist/liberal Catholic movement, perhaps the true opposite of Opus Dei.

Oh yeah, evangelicals are the worst. Or at least they're up there. Proselytizing is evil and forcing your religion on others is evil. And there's a reason why evangelicals are hated so much in the US. White conservative assholes.
