Some people post disturbingly angry comments on the Internet about something they can't stand. It's probably because they're seeking attention or trying to stand out, they may not be particularly enraged by the subject at all. My advice is to assume that they're not actually as angry as they are and just want other people to talk to them about a subject on the Internet. Hopefully thinking about this will help.
