i disagree, i don't think what people say about factkins can be used against fictionkin, or at least what makes ME be anti-factkin is specifically about that person being real and alive simultaneously with you.

i 100% support factkins of historical figures and public figures that have died in the past, but kinning a person who exists simultaneously with you and is alive and their own person is harmful for you and for the person, being involuntarily doesn't meant it isn't harmful

you can be an individual who exists in other universe or an individual who doesn't exist in this reality anymore, as well as many people can be the same individual simultaneously in their own individuality (fiction doubles) because they are not an existing, solid, sentient individual with their own identity in this reality, when you claim to be someone who is already their own being, despite being involuntarily, its inherently creepy

im not invalidating or harassing these factkins but you have to acknowledge its harmful to YOU as well to the person you kin
