There's also a tribal element, an "us and them" mentality that leads to this sort of thing. If you feel you belong to a certain group, you fight for that group. And the less you're exposed to other views the more extreme views tend to get. So it feeds on itself.
I mean I love the Trek, but I wouldn't be a Trekkie, and the opinion of Trekkies that's held by people in general makes me hesitant to mention this. But I could definitely see that people could be pushed the other way by the same reaction. So that even when they're not being attacked they're on a constant defense. But I would resist the temptation to Trek is the archetype, surely politicians and political parties get that cake for this?
