I'm not fond of the whole reducing people (people's identities, situations, etc.) to stereotypes/labels/catchwords thing. This is a bit of coping, in that the response was so over the top, never before seen, if I start by assuming a person is reasonable and civil, it's a very jarring combination, does not compute. But starting from a framing of extreme entitlement and unreasonableness makes such a response "not unexpected" and helps with the psychology, if that makes sense. My default setting absolutely is non-confrontation...otherwise, I'd not have gotten here to begin with.
