What was the original sin of Sodom?

It wasn't the act of ity that doomed Sodom, it was the public condoning of it. And the USA is following in Sodom's footsteps with the all this public acceptance and public condoning of uality by giving in to them and giving them rights etc that only heteroual couples should have. I know I will get a lot of negs on this comment, but truth is truth.
