We can't carry out Leviticus 20:13 without a Sanhedrin with full powers. In fact it was never carried out. But that doesn't mean we can't stop promotion of homosexuality in Israel.
Israel should reinstate the law against homophilia that the Knesset repaled in 1988. The law is a deterent even though it was not enforced.
Israel should ban promotion of homosexualty by government agencies. No more fag flags put up by taxpayers' money against their wishes. No more forced parades. No brainwashing on government televison.
