alt Hacker NewsThe question was "can you find me some reputable cryptographers that support your position?" which is just ad hominem and should be ignored as such, except it does indicate that the person asking it doesn't have any better argument than ad hominem.

> which is just ad hominem
I dont really think it is. The original person claimed that the reason dnssec was unpopular was due to FUD. I think in that context its a fair question to ask what experts think.
For it to be an ad hominem, the person has to claim that the argument is wrong because of who they are. But that is not the claim here. The claim is that their argument that dnssec hate is unjustified FUD is wrong because experts (who presumably by virtue of being experts) are not susciptible to FUD, also do not think dnssec is a good idea. Thus it is directly attacking the argument and not the person, and hence not an ad hominem.
If you think tptacek has no better arguments then you're sorely mistaken.
And implying that someone is unqualified is not in fact ad hominem. The desire to interview a disagreeing expert doesn't look fake either.
