Please don't respond to a bad comment with an attack of your own. Your reply would have been fine with just the second sentence, and better still with just the second clause of the second sentence.

It's also fine to simply not react. From https://news.ycombinator.com/newsguidelines.html: "Don't feed egregious comments by replying; flag them instead." a.k.a. please don't feed the trolls
