@guerrillarain I'm not sure, since a hundred folks will give you a hundred definitions of Queer.
Since I still want to give you an answer, the best I can do is thus: Queer ultimately described anything 'out of the ordinary.' But 'the ordinary' was essentially whatever a dominant narrative in the culture said so. This meant that all sorts of 'deviants' would get called queer, even if each one's subcategory isolated them. Queer as a self-applied label in this sense, would be a rejection of this assertion of 'normal', and to call it for what it is: an attempt at assimilating everybody into an ideology. Such queers would be aware of whitewashing, etc.
