This is hard for a short post, but I will give it a shot.

Early in Christianity (post 134AD) both Christians and Jews began to pass decrees and come up with practices that were designed to distance themselves from each other. Christians passed decrees about not eating the food of the Jews while the Jews began to wear Kippot because Paul wrote that man was not to cover his head. OK, like most they missed his point, he was talking about other authorities over us, not hats, still... they began to wear them to differentiate themselves from us.
Fast forward... some Jewish scholars have spent a great deal of time and effort creating doctrine that tries to show Messiah can't be God. I will show you 200 verses and then prove using science that Messiah can only BE GOD.... still, the Jews are raised to believe it can't be because if you open the door to 'can be' you open the door to Christianity, a place they do not want to go. Well, "Messianic Judaism" was originally Jews (mostly from Jews for Jesus) who repackaged Christianity to make it look more Jewish so they could convert Orthodox Jews. However, the Messianic Jews were still Jews raised in a culture that said, "God can't ever become a man." So... you simply won't find many who believe that Yeshua and YHWH are one and the same, God... a Spirit, manifested in the flesh.
Peace.
