Okay Campion. Let's see if I understand what you are saying... Are you saying that in this verse...
Mark 6: 3 Is not this the carpenter, the son of Mary, the brother of James, and Joses, and of Juda, and Simon? and are not his sisters here with us? And they were offended at him.
Are you saying that the Mary in this verse, and the SONS mentioned in this verse, were the sons of Mary, wife of ALPHAEUS?
Are you saying that and committing to that belief? Yes or no?
I think the verse is really pretty clear. The "Mary" referred to is the BVM. The James, Joses, Simon, and Jude mentioned are the "brothers of Jesus". It doesn't tell you (here) who their mother is. It doesn't tell you who their father is, either. You can no more assume that they are the children of Joseph and Mary than you can assume Lot is simultaneously Abraham's uterine brother and his nephew, because, after all, Abraham calls him "my brother".
But other verses (which I have already cited for you elsewhere) do tell us that James and Joses were the sons of Alphaeus and another woman named "Mary," later identified as the "sister" of the BVM.
BTW, unless you have ceased to believe in the virgin birth, perhaps you can explain to me why Scripture calls James the "brother" of Jesus when even you believe he was Jesus' half-brother. While you're at it, you can check out the case of Herod and his (according to Scripture!) "brother," Philip, who (according to Josephus), was really his half-brother.
