Earlier quoted context omitted.
Nobody's denigrating his faith, as much as his transparent attempt to leverage it for social credibility by advertising his piety on Hacker News while (evidently) doing nothing actually helpful. If that's not worthy of denigration, take it up with Jesus himself, who said pretty much the same thing.
Relevant verse: "When you pray, you are not to be like the hypocrites; for they love to stand and pray in the synagogues and on the street corners so that they may be seen by men. Truly I say to you, they have their reward in full. But you, when you pray, go into your inner room, close your door and pray to your Father who is in secret, and your Father who sees what is done in secret will reward you…" Matthew 6:5-6
There's just so much assumption and ill will in this subthread. Get a grip, people.
