It can be tough to separate an opinion you hate from the person who owns it, but it's kind of necessary in order to have a civilized disagreement. If you can have a good-natured laugh over your differences then you're doing it right. I've been guilty of this in the past myself. Fact of the matter is Nam and I hate to call you out on this because you can be pretty funny, but you start off on a personal note under the context of putting the trolls in their place. The only problem is that the true "trolls" create disagreement and misery for its own sake. I don't think any of us really fit that category, but actually care about these various properties.
Not a single aspect of this is good natured when you start throwing those classic perjoratives of yours, especially when it's entirely unprovoked outside of simply not sharing the same taste across many threads. I'm not asking you to change your core beliefs, but how about resisting the urge to engage in pointless dogfights? A good ribbing is fine, it's just that you go for the jugular every single time dude.
