Vidiot : Hasn't some historical evidence been found recently suggesting that a lot of the "persecution" stories the early Christians told were propaganda?
That's certainly the contention of the two scholars in the above attached argument. They are not alone in their viewpoint. But I know of no 'historical evidence' as mentioned in your post. Rather the viewpoint is inferred from the extant Imperial records.
I drew attention because as JWs we knew we may have to endure - or worse, see our kids tortured in front of us. Of course, the JWs are not alone in their boast of being persecuted for his name's sake, and there is something of an argument that it all harks back to second temple Judaism and the Maccabean rebellion in which some Maccabean supporters became 'martyrs.'
