Supersoulty, who are you to judge the personal religious beliefs of the delegates? I, for one, would never dare assume that someone's cheering for the mention of God is fake. All of a sudden you are an expert on the personal religious views of these people?
I do think there is something contrived about far-left Democrats posing as religious people.
I don't know about their personal beliefs, but their policy agenda, and the attitude they project, is not only indifference to the dominant religion in this country, in its various forms, but outright hostility. "Christian" is a bad word in left-wing Democratic circles, and anybody who shows any sign of Christian religious beliefs is ridiculed in this circles. The only thing that the far left finds immoral is being "judgmental" unless of course they are the ones making the judgments.
