It's not about whether the cause is justified but whether it is true.
To be true then mistakes and lies would have been assessed and dismissed as being likely risks - how has this been done in respect of the NT?
Eg we see Muslims fighting for their religion. Therefore it is likely that when the Koran says Mohammed told his followers to fight for their religion, Mohammed actually did say that.
How do you know Mohammed actually said that? You (or Muslims) might like to believe he did but you/they don't know he did, as in having knowledge, so there is reasonable doubt.
We read of early Christians being stoned by the Jewish authorities, therefore it is likely that the gospels are historical documents (according to the argument made in post 81).
So what? That people suffer for a cause may say something about the people but it isn't confirmation of the truth of their cause. You need to be careful with the term 'historical' - the NT is certainly a historical document given the passage of time since it first appeared but that is very different from presuming its content is all established historical fact - for example, you won't find a professional historian claiming that the death and claimed resurrection of Jesus is historically true.
The content of your #81 isn't an argument: it is just naive assertion.
