Nah!
Judaism is fine, Christianity came along and insisted it was something it wasn't, to suit themselves and their beliefs.
Unfortunately, Rose, the people who came along and insisted that Judaism was 'something it wasn't' (to use your terminology) were Jews.
It was frowned on at one time to even look at the Jewish religion, you were supposed to except without question the Christian way of seeing Jews.
(As slightly stupid people who mindlessly followed laws)
That only started about 300 years into the church's history when the Romans decided to claim Christianity for their own.
Christians in authority created an image of Jews that still exists today, even among people who no longer believe in any religion.
Sadly, this is true; note though that there is nothing in Jesus' or any of the New Testament teachings to support this attitude.
Christians do like to give the impression that charity and love were things that sprang up from Jesus and that Jews just follow rules by rote without meaning.
The problem is that the way that the Jewish authorities of Jesus' day interpreted their fith, this was very much the case - hence Jesus' lambasting of said leaders in the way he did. He actually pointed out that 'true' Judaism was far more a matter of laws being made to support people rather than the 'Man being made for the Sabbath attitude that they displayed.
All the loving things Jesus taught, came from Judaism.
Excepting maybe loving your enemy, but I guess that was Jesus's spin on it.
Except that this is an Old Testament principle that the Jewish religious leadership had chosen to set aside
If you look up Rabbi Hillel and the golden rule you will see what I mean
I agree, Hillel was old hat as far as Jesus was concerned.
