The idea that Christianity is "unpopular" or even "persecuted" - here in the US especially - is absolutely ridiculous. A very large majority of the world population is religious, and of that world population, 1.5-2.5 billion consider themselves Christian - that's between one quarter and one third of the world population, making it the world's largest religion.
I am ethnically and culturally Jewish, and grew up surrounded by a diverse blend of Jews, ranging from haredi (ultra-Orthodox) to Reform (liberal/modern) and Reconstructionist (so liberal/modern they can't seem to decide if they technically believe in God or not). My mother was the president of a large Conservative (in-between Orthodox and Reform) congregation when I was small. I still love to dance Ushavtem Mayim and the Hora, celebrate Hanukkah and Passover, and swear in Yiddish; however, I found (and still find) the religious rules stifling and pointless, and the beliefs make no sense to me.
As far as the best secular Biblical scholars can tell, Jesus was a radical Jewish religious reformer with a message of extreme kindness and forgiveness, communal living, peace, compassion and understanding. He embraced those whom others shunned - prostitutes, Samaritans, tax collectors. He was not a miracle worker, and never claimed to be a mashiach, the son of God, or divine in any way. He never intended to found a religion, and would very likely have abhorred the Pharisaic legalism Christianity tends to embody. There is some debate over whether he preached an apocalypse; it is fairly certain, however, that Christianity was an invention of his successors - particularly St. Paul - not of Yeshua of Nazareth himself.
Jesus was obviously a great man. That being the case, I wish the people who take it upon themselves to follow him would actually follow his teachings. How he died, and whether he was resurrected and now sits at the right hand of God, is irrelevant; forgiveness, compassion, acceptance of the societally outcasted and marginal, etc. are the real "Christianity" in my book.
