I asked a question and gave part of the reason I was asking. How is that arguing?
How did you use logic to arrive at that conclusion? Please show the steps.
7 versions, not one translates "adelphos" as cousin. Perhaps you know of a version which does?
KJV Galatians 1:19
(19) But other of the apostles saw I none, save James the Lord's brother.
NIrV Galatians 1:19
(19) I didn't see any of the other apostles. I only saw James, the Lord's brother.
NIV Galatians 1:19
(19) I saw none of the other apostles—only James, the Lord's brother.
ASV Galatians 1:19
(19) But other of the apostles saw I none, save James the Lord's brother.
ESV Galatians 1:19
(19) But I saw none of the other apostles except James the Lord's brother.
ISV Galatians 1:19
(19) But I did not see any other apostle except James, the Lord's brother.
NET Galatians1:19
(19) But I saw none of the other apostles except James the Lord’s brother.
The Greek word "adelphos" occurs 104 times in the NT. I cannot find one single instant where it can be conclusively shown that adelphos means "cousin" vice "brother." But I can find several occurrences where it can be shown to mean brother.
Mat 4:21
(21) Going on from there, he saw two other brothers, James son of Zebedee and his brother John. They were in a boat with their father Zebedee, preparing their nets. Jesus called them,
Mat 22:24
(24) Saying, Master, Moses said, If a man die, having no children, his brother shall marry his wife, and raise up seed unto his brother.

(25) Now there were with us seven brethren: and the first, when he had married a wife, deceased, and, having no issue, left his wife unto his brother:
Mar 6:17-18
(17) For Herod himself had sent forth and laid hold upon John, and bound him in prison for Herodias' sake, his brother Philip's wife: for he had married her.
(18) For John had said unto Herod, It is not lawful for thee to have thy brother's wife.
Mar 12:19
(19) Master, Moses wrote unto us, If a man's brother die, and leave his wife behind him, and leave no children, that his brother should take his wife, and raise up seed unto his brother.
Luk 12:13

Luk 15:27
(27) And he said unto him, Thy brother is come; and thy father hath killed the fatted calf, because he hath received him safe and sound.
Joh 11:2
(2) (It was that Mary which anointed the Lord with ointment, and wiped his feet with her hair, whose brother Lazarus was sick.)
I suspect rather that you have assumed Mary is their mother, and that would naturally make them His younger brothers, or you have assumed that they were younger, which would naturally make Mary their mother, but you can't arrive at both with just logic. You have to make an assumption first.
See above.
Only if sons of Mary.
I've never claimed they were anything other than Jesus' brothers, just not sons of Mary.
Perhaps you can explain to me how James, Joses, Simon, and Judas, Matt 22:25, can be Jesus' brothers but not sons of Mary? You assume that one of Mary's sisters or brothers had 4 sons, that they lived close to Mary and would accompany her to where Jesus was and that Mary's neighbors would know that they were cousins of Jesus. That's a lot of assumptions with zero evidence.
Ad hominems are indicative of weak arguments. If you read my earlier posts in this thread, I've explained why I have found the traditional view to be more consistent with Scripture than the post-reformation view.
I've heard that before but repeating an old adage does not make it true.
