To anyone attacking me, my comment was sarcastic and intended to point out the xenophobia inherent in the OPs statement. I wasn't saying that "I" thought minorities should be killed, I was dryly saying that the "ideal world" spoken about by the OP would be a horrible one in which many innocent people would die.
For that matter - what kind of terrible person would publicly go on Hacker News and say that they think minorities should die? Why would that be your first thought?
