Ouch! I'm not overly enamoured with posts about video games, but then I generally avoid threads with a video game theme. It's a fairly straightforward process. When you log into the forum you get a list of threads with titles that generally explain the topic of conversation. I'd suggest you avoid any with 'celebrity' or similar terms.
People are always going to debate people who are in the limelight. I have family members who work in similar careers and it comes with the territory. I've seen things posted about them on random message boards and it's the same as people discussing someone in the real world. Just a load of gossip and opinion and nothing else. If people try to state their opinions as fact, then yes it becomes an issue (media, for example). But I don't think anyone on this forum is trying to do that.
