I tend to rank religion by how much they hamper human progress in general.
Religions that may be vicious but also seem to be lacking in the ability to gain in scale don’t hamper human progress very much.
Religions that tend to hold sway only in areas that are backward and primitive is less dangerous to general state of human progress than religions which are likely to gain political power where institutions of human progress are concentrated and thus can apply their malevolent influence more directly upon engines of human progress.
So I have to say Christianity ranks far and away as the worst and most dangerous, even if it at the moment doesn’t seem to be quite as vicious as Islam.
