A lot of the so-called fights wouldn't occur if the 2 or 3 or whatever people were left alone to discuss whatever they wanted to discuss. It's when someone labels it as a fight, then it's seen as a fight, when really it wasn't a fight at all, just strong opinions discussed in a manner that the individuals best knows how.
If people aren't free to fully express their viewpoint, even if it's positive or negative or whatever, without fear of the thread being locked or someone jumping the gun and getting their facts all screwed up, then a situation has been created where a situation never existed and a certain level of angst boild over onto another post.
There's a lot of so called do-gooders out there who think they're doing good but are in fact shit-stirring. You only have to look at the recent fanvideo thread for a classic example of that.
