Sometimes commenters all over the internet write like this because they just got incredibly jealous after reading the parent post. I've been thinking more and more about how most posts are jealous or depressed outtakes against the world, system, or other person. This fundamental human behavior won't change, and is as reflexive as a monopolistic company reacting to a press release, proving the parent correct despite their scathing response of the child.

It's worth noting that 4chan and Reddit also live here because both sites are insufferable.
