The dalish demonstrate time and time again, that they are the epitome of all three of those things. Every time you enter a dalish camp in DA, as a non-elf, you get death threats. Velanna just murders random humans for no reason and then there's Zathrian of course.
The Dalish are the targets of violence, and have been since the fall of the Dales. An outsider who comes to them in peace is the exception, not the norm.
Also, Zathrian cursed the humans who murdered his son and raped his daughter, while Velanna was mislead into thinking humans killed her group and kidnapped her sister; I don't excuse their actions, but it's not as though they are black hat villains out of a Saturday Morning Cartoon.
