When a thread comes up about a group/artist who you hold a negative opinion on, do you:

a) Ignore it, not post, and generally let it slide past without any input by yourself

OR

b) Post a negative comment in the thread, state your opinion, knowing full well that its bound to irritate some people who are fans of said group/artist, often leading to some drawn-out and ultimately fairly pointless row.

Just interested to basically examine what makes different people respond to threads.
