Otherkin

There's been some Discourse™ lately on Tumblr about whether it is possible to stop being otherkin in any circumstances. All parties seem to basically agree that if you can easily "turn it off" then you weren't actually otherkin (or some specific thing wasn't actually a kintype) in the first place, but do not agree on whether it is possible to stop or change as a result of a long process of personal transformation ("ego alteration", one participant dubbed it). Your thoughts?
