Comments from banned users get killed automatically. I've unkilled that one. In the future, if you see a comment that shouldn't be [dead], that's what the 'vouch' feature is for: click on its timestamp to go to its page, then click 'vouch'.
You're also welcome to email hn@ycombinator.com and let us know, so we can unkill it. But please don't noise up the thread by posting offtopically about it.
As someone who regularly defends some pretty vile shit for ideological free speech reasons, it makes me uneasy how "freedom of speech" is starting to sound way too synonymous with "unrestricted license for nazis and assholes to spread their ideology and hatred even on private services".
The real damage neo-nazis can do is to turn people against the concept of free speech.
So I suggest we call this "Freedom of hate", instead.
