Jesus rejected certain aspects of Jewish practice and said who he thought he was but he did not meet the precise criteria to be considered the Messiah, hence, he was rejected.
That rejection has cost us quad-upteen-trillions in life and property and peace.
I do not want to get into polemics here with you because I respect your belief. Will you respect mine? Note that I do not “offer” you anything, no cross, no Judaic belief, no promises of anything because we Jews do not proselytize. I will not tell or sell you my faith because it is not for sale or for the highest bidder. Nor is it in my interest to convince or persuade you that I am more right than you. You offer me the Cross but I have the one and only G-d who's name we do not even mention, no "Jehovah" (by the way, that is not the correct pronunciation of His name). What does it mean to be "jealous" for the name of the Lord? Serious Orthodox Jews are not "jealous" in the sense that I understand it. Orthodox Jews reject your entire thesis out of hand. I at least am in a dialog with you. They (the Orthodox) would not even engage you on this subject. So, what do we learn here? Tolerance.
I mean, like I discovered that the Lord was more interested in His human creatures than simply wanting them to hope He might get around to doing something nice for them. This was clear from the very start of the bible events. An infinitely powerful God who stooped to personally visiting a pair of sinners in a garden, then later to telling (alas, in vain) Cain to cheer up and try again the right way when his first sacrifice failed, has to have a good reason for reining in His own majesty to the extent of making such an encounter even possible without killing the person who was encountered.
Christians boldly assert that the reason was revealed to them. Differ if you must, but you cannot deny the utter change of world view it imparts in a life; a horribly feared God becomes a fantastically loved God. Those treating the Christ as some club mascot to be fanatically defended from desecration by outsiders are at best very weak, and likely have no clue at all. You are safe (and wise) to ignore them. Listen to the ones who show the love, who will forgive you when you have cursed them out to the maximum. Those are the real Christians.
