Some people are so earnestly self-righteous that they just can't help embarrassing themselves. This particular example, a man named Adam Smith, is an adjunct professor at a college in Arizona and also CFO/Treasurer at Vante Corp. His idea of standing up for his convictions is to harangue a young woman, an employee at Chick-fil-A who has nothing to do with her employer's views on gay marriage.
Nor, by the way, are the CEO's personal views on gay marriage the views of Chick-fil-A as a corporation. CFA doesn't discriminate in their hiring nor in whom they will serve, but a lot of news coverage is treating CEO Dan Cathy's remarks about his personal beliefs as though they were corporate policy.
Anyway, this guy is so infatuated with his own moral superiority that he videotapes himself preparing to lecture a young employee on the hatefulness of her CEO's stand for traditional marriage and how he doesn't know how she can live with herself working for this company:
This noble warrior against hate then posted the video on YouTube where it outraged many, including his bosses at Vante who fired him yesterday, probably for being an obnoxious jerk.
