Well, Arda mentioned it already: don't be afraid of flagging. I have removed the heavily discussive portions, but I did not remove all of the author's opinion. There were parts which flavour the author's words, but do not incite discussion in themselves because they're still surrounding a question. But I felt that the presence of those two portions I did remove were sufficiently excessive and tangential to the question.
The comments from yourself and DJClayworth illustrate the reality of the situation.
There are plenty of places for you to express your opinions on online gaming. This is the place where you can ask questions. – DJClayworth
@Mike Ultimately, this is a Q and A site, not a forum for opinions. While your discussion topics are interesting, this isn't the place for them. Here, they only serve to dilute the question itself. – sjohnston
Basically, it's a matter of noise clearance. If it detracts from the question, it should probably be edited. Whether it's giant subjectivity or just a big tangent from the real question, removing it is more useful than leaving it in. As far as etiquette in doing this, asking the user to politely edit it themselves is always a nice thing to do first. But make it clear that it really isn't the intent of the site to be a discussion forum, so if they don't do the edit then someone else will.
People come here for answers to questions, and it doesn't help them find the questions with their answers if it's buried in a whole bunch of junk. If it involves heavy editing to remove that junk, just make sure you don't lose the real question in the process.
