Well if they denied him at the time, I don't see why anything would have changed since then. Even though a lot of them didn't deny him, especially considering Jesus was ethnically a Jew.
Plus, Jesus's message of peace and loving your enemy and nonresistance has clearly made very little traction, even among those who claim to 'love' him and follow the religion literally named after him (Christians who support the death penalty? The **** is all that about?).
You might find this group interesting, too:
Well, Jesus preached tolerance and pacifism, and his arrival signified a move away from the strict laws of the Old Testament and promoted nonresistance and peace. Jesus did not kill, nor would he raise arms against those coming to arrest and execute him:
10 Then Simon Peter, who had a sword, drew it and struck the high priest’s servant, cutting off his right ear. 11 Jesus commanded Peter, “Put your sword away! Shall I not drink the cup the Father has given me?”
If you take the strict dogma of the Old Testament as your main moral rulebook, then you may as well not be a Christian, because the whole thing of Christianity is to be like the Christ: forgiving, caring, an emissary of peace, and someone willing to sacrifice everything that is theirs, even their life, to protect or empower humankind.
The main reason Judaism has not taken on Jesus as their Christ is purely a historical thing. They still are Godly people, and as long as they are caring and good people, they will be admitted to the Kingdom.
