What changed in the 1970s regarding sodomy laws in the US?

Illinois became the first state in the U.S. to get rid of its sodomy law. It did so in 1961, when it adopted an overall revision of its criminal laws. The revision closely followed the 1955 recommendations of the American Law Institute, a group of distinguished lawyers and law professors. Idaho passed a similar revision, but when the legislature discovered it had repealed the sodomy law, it repealed the entire reform package instead.
