Two things–, no, three.
First, the best way to get over being self-conscious/upset about “too many” kintypes, is the same way to get over anything that embaresses you. Own up and embrace it. Its not something you can change, so there’s no need to feel self conscious about it.
Second, at this point most of the kin I know have multiple kintypes.There are lots of potential reasons for this, depending on if you buy Spiritual Brand Kin or Psych Brand Kin, but either way, that’s just how it is.
People who have only one kintype and are snobby about it are largely the same type of people who are snobby about anything. They can go finish their MFA instead of giving you a hard time about it.
On the other hand if you really think you have ‘too many’ kintypes, maybe its worth inspecting/reinspecting them to make sure they’re really kintypes and not just things you like, or things you thought were kintypes but then you got more clarity and realized it was actually X instead of Y, but you thought it was X because X and Y share a lot of characteristics.
(with apologies to MFAs who are not snobs <3 you rock)
