Are we gonna address what 'MARK' has asked about with this thread and quit getting off topic? He asked specifically about groups or any group with the stated specific intent to bring 'Christianity' (not religion or any religious system, but specifically Christianity) to it's ultimate demise, not wether or not there is religious persecution.

Persecution and/or oppression and/or repression there definitely has been historically and even currently, especially under socialistic or communistic forms of government, but what about the specific question of this thread?
