What are your thoughts on the complaining?

I don't have a problem with negative threads because I don't even open them if I disagree with the topic. The only problem I have is when sometimes a person is so upset about something that they open several negative threads about the same exact thing on general discussion. I wish that we could ignore threads as well as people.
I'm an avid user of ignore button and if there wasn't an option to do so I would never even come to this forum, I don't want to spend my free time dwelling in misery. One of the reasons I joined this forum after just lurking in here now and then was being able to use the ignore button.
