Your basic argument is that Paul is possibly not a Roman citizen because he makes no mention of it in his epistles, that's an argument from silence and is as weak as those who say Jesus doesn't exist because Paul doesn't give firsthand information about Jesus.
Actually, I said that it is most probable that Paul wasn't a Roman citizen as he doesn't mention it, is not treated as one, and that there is no real evidence for him being a Roman citizen. Again, a large portion of my argument has been that Paul is not treated as a Roman citizen.
This is exactly why I don't think you actually read the OP.
And that we can't use Acts as a source because Acts isn't as reliable as Paul when it comes to biography, that is poisoning the well against Luke as a reliable source. I say Luke maybe reliable because in his book he is not just using Paul as his source material but using other sources as well as he did when the he wrote the Gospel. Of course his version will be different from Paul's because he is using other sources, some who saw things from a different perspective than Paul. What's wrong with that?
It's not just me who thinks that Acts is not always reliable when it comes to Paul. And I backed that up with logical arguments (one being that Paul and Acts contradict each other, and that Acts has a history of making things up or exaggerating points), as well as with a variety of scholarly opinions.
I'm not poisoning the well. I'm simply stating what scholars agree upon when looking at Acts. That is why I gave citations of the works that I was using, including page numbers so others can actually check them out (and if one doesn't own those books, one could probably find them in a local library).
So without additional support for Acts, we can't take it to be historical fact. It is speculation. That really is how we judge other sources as well. We don't take one blindly.
It really does appear you don't understand my arguments at all.
