The “Homo” Sin Causes Expulsion from the land of Israel

Vayikra – Leviticus – Chapter 18
You shall not lie down with a male, as with a woman: this is an abomination. And with no animal shall you cohabit, to become defiled by it. And a woman shall not stand in front of an animal to cohabit with it; this is depravity. You shall not defile yourselves by any of these things, for the nations, whom I am sending away from before you, have defiled themselves with all these things. And the land became defiled, and I visited its sin upon it, and the land vomited out its inhabitants.
Rabbi Melamed brings up some other arguments against those that try to give legal standing for the “Homo” Sin

Excerpt:

In the same manner that an individual must struggle not to covet the belongings of his neighbor – a sickness known as kleptomania – one must do battle with the homosexual urge: through education and law; and if that does not work, through psychological and psychiatric care. If there are certain individuals who have been born with such a strong homosexual drive that they are unable to overcome it, then this is very painful and their plight certainly awakens pity, but the fact that they are unable to overcome these desires does not rectify such behavior.
