>>it preaches zero in-grop preference
no, it doesn't do that. Their group is Christians, which is why they destroyed all pagan worship, or why they banned usury among Christians, or why they evangelized.
You are making a fundamental mistake in assuming that the only valid group is a racial one, when race wasn't even a concept back then, more like ethnicities, which were also poorly defined.
>>it is targeted at Rome
no, it wasn't "tagetted". Rome accepted Christianity after an emperor prayed to YHWH, in their land, and won a battle, which made him believe that these 2 things were related.
>>Rome adopts it and collapses in under a century, Jews survive, and Synagouges pop up all over Europe
Rome did not fall as a consequence of Christianity, they had been experiencing problem for several years and had many crisis before. Like every other empire, their oppressive practices towards conquered lands gained the enmity of the oppressed, their losses against germanic tribes were also devastating and the invasion by barbarians, the insane amount of corruption in the governmental body of the empire, etc.
To say that it was "christianity" is utterly retarded.
