So killing gays is ok then? Yes or no?
BADecker stated that the laws in Leviticus were given and apply to ancient Israel.
Let's see what the Orthodox Jews say about this topic.
HOMOSEXUALITY IN ORTHODOX JUDAISM

THE CONTEXT AND REASONS FOR THE TORAH VIEW OF HOMOSEXUALITY
The Torah calls homosexuality a Toaiva-abomination. What does it mean? Usually, the Rabbis do not explain the meaning of Torah words. And the meaning of abomination seems reasonably clear -- it is abhorrent to God. But in this case, the Talmud does offer a specific explanation. Based on a play on the Hebrew words, the Talmud says that in the act of homosexuality, the person is "straying" What does this mean?
The commentaries on the Talmud say that by abandoning heterosexual sexual relations, the person is straying from one of his prime goals in life -- to procreate and populate the earth (Genesis 1:28). We will amplify this theme below, but this explanation does not seem to be the "abhorrence" that the word "TOAIVA" implies in the simple meaning. Thus, the classic explanation of why homosexuality is prohibited in the Torah is because of "straying" i.e. failure to populate the earth. The Chinuch explains that any "wasting of seed" on homosexual relations is preventing procreation and inhabiting the earth, the prime directive of man. This "prime directive" is echoed by Isaiah in describing the purpose of Creation -- "to be inhabited."
This explanation does not point to the "unholiness" of the homosexual relationship, but, rather, the violation of man's purpose on earth. We may be able to understand the Torah view of homosexuality better if we compare it to other sins in the Torah that are also called Toaiva- abomination. There are numerous other references to deeds that are described as Toaiva- abomination. By examining each one, we may be able to ascertain what they all have in common.
Desiring and taking idols of the nations that the Jews conquer is considered a Toaiva- abomination. Eating non-kosher foods is also called a Toaiva-abomination. There is a general statement that ALL the customs of the Canaanite nations are considered to be Toaiva-abomination. Then there is a general warning not to learn or copy the Toaiva-abominations of all the Cannanite nations. This is followed by some examples (noted above), including child sacrifice to their gods, using a seer or "magician" to contact the dead or predict the future. Then God says that it is BECAUSE these nations did all these acts of Toaiva- abomination that God is letting the Jewish people inherit the land.
What do all these acts have in common? They are pagan customs of the societies whose values are antithetical to Judaism. God emphatically warns the Jewish people not to learn these customs or follow these values. Based on this, homosexuality, also called Toaiva-abomination, can be understood to be a societal value and sin that is alien to Judaism and Jewish values, and should not be "learned" from the societies where the Jews have lived or have conquered.
The other Torah, Talmudic and Midrashic references to homosexuality also elucidate the overall Torah view towards homosexuality. Although not expressed explicitly in the Torah, the Rabbis understood that, according to Rav, Potiphar bought the Hebrew Joseph specifically for homosexual purposes. This is significant, as it implies that homosexuality was prevalent in Egypt at that time. Thus, when the Torah later on commands not to imitate the ways of the Egyptians (and Canaanites), this could also include the common practice of homosexuality that was found in these societies.
...
In the society of Sodom, the Torah clearly says that the townspeople demanded that the strangers be given to them for homosexual purposes (the verb "knowing" in the Torah is frequently associated with the sexual act - - see Genesis 4:1). This was apparently common practice in that society, and hence the origin of the term sodomy. This is one of the main reasons that the city was destroyed very soon thereafter.
All of these Torah examples have one thing in common: homosexual activity is common in these foreign societies and is abhorred by God, and all of these societies were eventually destroyed. Thus, once again, shows that Jews may not engage in such activity, and imitate the mores of these foreign societies.
The overarching argument appears to be one of willful self destruction.
That if a society chooses to embrace Toaiva-abomination be it child sacrifice, beastiality, occultism, or yes homosexuality that society will sooner or later be "distroyed by God".
It would cease to exist presumably by not fully understood cause and effect mechanisms that undermine something necessary for society to survive.
Now if you believe the Bible is arbitrary man made rules you reject that argument. The multiculturalist for example argue that all cultures and practices are equally valuable. One does wonder how they would deal with child sacrifice if all the societies practicing it had not already been destroyed.
Regardless we live in a secular society where homosexuality is accepted and celebrated with frequent parades.
Will that acceptance cause growing problems and gnaw away at the foundations of our society over time? The answer to that probably depends on whether you think the Bible is the word of God or arbitrary rules.
