Jesus was the one and only perfect Jew; how could He hate Judaism?
You're being disingenuous.
He hated what was being taught and practiced
as though it were Judaism, and
in the name of Judaism. It is precisely what is today
referred to as Judaism by Jews themselves, i.e., the 'Traditions of the Elders," codified in the form of the Talmud.
There is no longer any authentic Judaism possible, since any who identify as a Jew, yet deny Christ, is with anti-Christ, so says Jesus. And any Jew who acknowledges Christ has become a Christian, and is no longer a Jew in the sense of adhering to the Judaic religion, which prefigured Christ, but was brought to an end with Christ.
