I would say that these forums are open to everyones comments. If they are offensive they are sometimes removed. If they offend the reader, the reader can then stop reading that particular thread. I think 99% people here are responsible posters/readers/lurkers.
To call people childish for their posts is silly as they probably are children.
I have a new feature added to my computer this year. When I get in a thread that looks to be going bad, I scroll using this wheel on my mouse and I get past it.
