Even though Leviticus isn't talking about the Temple, it never the less is an important consideration for the impurity of all that live there. The reason being that all Jews who reside in the Holy Land are ritually impure and therefore should in theory be expelled from the land by G-d. That of course has not happened. As a rule, the opposite has occurred which means that according to Jewish prophecy, the redemption is close. This is why I brought it up.
So, here's the question: are their practices officially permitted in modern Israel today that Leviticus clearly calls abominations? If there are, then, logically, such practices should be officially banned for the health and security of the nation--if you believe in Leviticus.
You have no argument from me as to banning the practices that are forbidden in the Torah. The problem is convincing a largely secular population of its necessity. Even if you were to pass these laws, would people live with them or violate them anyway? People largely govern themselves. As you can probably see (easily) that there has never been a clear consensus among Jews to do these things unless G-d has revealed himself.
Now, I take it that the "footsteps of Moshiach," that you mention probably is a reference to what Christians would call the coming of the Messiah--correct? Well, if we can agree of this, the Bible says he will certainly come . . . on The Day of the Lord--but that won't be a good time for those dwelling in Israel, according to the New Testament.
By Christian theology, you would be correct. By Jewish theology not necessarily so. Jewish prophecy does not call for the necessity of the destruction of Jews so that Moshiach will come. The enemies of the Jews have much to fear though. We will have to agree to disagree on this.
