So after four years of comments on Hacker News I've finally posted my first negative-voted comment. Am I right in interpreting this to mean it's perfectly acceptable for the grandparent to write something insulting by saying : "all kosher food does is restrict consumer choice to products sanctioned by a small religious mafia perceiving a tax on every products they "authorize"." But pointing out the inherent hypocrisy in the grandparents post as per my comment above is out-of-bounds? Edit - my first post was rated at -3 when I wrote his second comment. But was up voted to -1 by the time I hit Submit.
