Technically speaking, an executive decision is not a change in the law and change in executives can undo the previous decision. However, the wind is blowing in the direction of equality so this is good news. The law, however is another and amazing thing. To justify racial marriage laws in 1940's, a judge actually said in his ruling that "almighty God placed the races on different continents for a reason." So…..despite appearances that is cultivated by judges, legilslatures and lawyers, the law is often not neutral. But "Cheers" for any progress!
