Christianity is a religion of forcible conversion or face death.
With malice towards one & all
The practice of genocidal evangelism was widespread throughout Europe and it is no exaggeration to say that without this initial spurt of violence and savagery - which was justified by quoting selected Old Testament scripts which in turn quoted the Biblical God exhorting the Hebrews to kill his enemies - it is unlikely that Christianity would ever have displaced the original White Indo-European religions.
Certainly none of these original White religions ever contemplated converting non- believers upon pain of death, and were culturally and physically unprepared for the fanaticism engendered by a Middle Eastern religion such as Christianity. It is always worth bearing in mind that none of the original White religions - be they Odinism, or any of the Sumerian, Egyptian, Greek or Roman Gods - ever had a war fought in their names, or ever tried to convert adherents upon threat of death.
