Of course Christ was both man and God, and in His humanity He lived as we all live. What I found disconcerting about your listicle is that it is fraught with points that seem superfluous.
1. So the Church in the West and its artists depict Christ in a way that reflects themselves, what is the issue? The Eastern Church and others depict Christ in icons, which perhaps are closer to what you are asserting in that Christ was born a Jew. The other thing is that, as a Catholic, I know there have been times throughout history wherein Christ appeared to mystics and others, many times in appearance resembling that person's nationality. The Blessed Virgin Mary has appeared to many throughout history and the seers, in being asked to describe her, give different accounts. Think Fatima, Guadalupe, Lourdes, and Knock, as examples.
2. "Jesus was a common name".....what is your point?
3. Various dictionaries define "refugee" as "a person who has been forced to leave their country in order to escape war, persecution, natural disaster....." Refugees rarely, if ever, return to their homeland. The Holy Family did.
4. Little is actually written about Christ's boyhood, excepting the Finding of the Child Jesus in the Temple (St. Luke 2:41-52). Various authors have written about what it was like to live at that time. As Christ was like us in all things but sin, it is likely that he was raised in a regular Jewish household, following the norms of the time.
5. Ah, here it is problematic. Let's begin with the actual definition of "brethren". Dictionary definition, the word brethren is "used chiefly in formal or solemn address" (think many sermons/talks can begin, "Dear Brethren"), or, the definition continues, "in referring to the members of a profession, society, religious denomination or church".
The reference you make to St. Mark 3:31-35 has been explained by Bible scholars many times. The footnote from my Bible actually says explaining the word "brethren" as being relatives of Jesus, not blood brothers. "The wider use of the term was common among Jews. Jesus does not disclaim the bonds of physical relationship, but He seizes the opportunity to give a lesson on the greater dignity of spiritual relationship."
I also find it difficult to see your assertion that the Blessed Mother and St. Joseph might have been embarrassed at having a child "claiming to be the Son of God". Is that not what the Pharisees wanted Pontius Pilate to inscribe on the Cross after they had Him executed? Certainly St. Joseph and the Blessed Mother knew Christ was the Incarnate Word, and that His presence fulfilled the Promise of Abraham, and as far as I have learned, the Child Jesus never put forth that assertion among His "brethren" growing up.
A good read and explanation as to the idea of Christ having brothers and sisters can be found here:

6-8. As Christ was like us in all things but sin, why is it hard to think that He did not participate in social gatherings? Think Wedding at Cana. Once St. Joseph died, and Christ began His ministry, it is only reasonable to assume that He would rely on the hospitality of others, especially those followers who had means to offer shelter and food.
It was part of His ministry to bring the Good News to all people, not just the elite and those with social and political prominence. Truly leading by example in showing compassion, kindness, and concern for the disenfranchised.
9-10. The obvious and most accepted belief was that Christ was a "criminal" and needed to be executed. However, the faith of Abraham, Isaac, and all the nation of Israel had been perverted through the centuries, so that the people favored by God were unduly burdened by laws and regulations made by those who profitted by it. (Not unlike today). By the time of Christ, there was little resemblance to the holy nation of the Old Testament (as flawed as it was it was still holier than when Christ was born). A great read on that whole time, and especially the final 18 hours of Christ's life is "The Execution of Jesus, The Christ...The Medical Cause of Our Lord's Dealth During His Illegal Crucifixion" by Mark Kubala, MD, FAANS, FACS.
Anyway, thanks for the read and the opportunity for me to do some thinking about the dual nature of Our Savior.
