Well, I would be remiss if I didn't say that I also take you seriously and respect you. I also don't think you are wrong... at least in the way you are looking at it. I think there are other ways to look at it, though. Still, no excuse for me being grumpy.
I didn't see your original message but I'm sure it was well-intentioned and wrong. I am wrong often too. Just not this time.
Taking back an HN post you think will be taken as uncivil is a strong move. Respect for taking the community seriously. There's nothing personal in my criticism of encrypted email; it's the technology I hate, not the people behind it.
