I think it's pretty obvious that humanity is a culture, and it's not a very good one. I'm otherkin; I don't identify as human. I wouldn't want to be a human, because humanity as a construct is used to justify so much evil. When people wanted to do the slave trade or the holocaust or colonisation, they did it by stripping humanity from these groups. Because human culture says it's acceptable to treat nonhumans this way. And that's why I want nothing to do with such a toxic construct. I'm not interested in appealing to colonial values.
