Usually, POC are completely untouchable in SJW circles. But Chloe has two trump cards that are rarely combined. The first being upper middle class white girl trauma. When presented in an unattractive package, white girl trauma is rarely enough to sway SJWs into throwing POC under the bus. It is much cooler to support Big Chief than to support a lone girl crying on Tumblr, particularly if she has no following and is in some way physically unattractive. At least Chief has pretty feathers and a dream catcher.
However, Chloe's second trump card is popularity and a semi-attractive package. She has a following. She is arguably attractive; at least she is not significantly unattractive if we ignore the teeth, the psycho eyes, the head shape, and the stick figure but to each their own. She has all the cool things Big Chief had and more.
When these trump cards are combined it is enough to sway SJWs into supporting Chloe over POC. Because we're forgetting that the majority of SJWs are white girls trying to prove a point. Often, their activism is teenage rebellion and at heart they don't really care about the marginalised groups they use to feel better about themselves.
Chloe gets away with pretending to be Native American, Indian, ambiguously black, and an unspecified type of Asian, and will continue to get away with this. No one bats an eye because she's allowed to be racist if she's fucking coping ok?‽!1?1?
By extension, Nan is allowed to be a pedophile because she is within Chloe's orbit and now has a following. By supporting Nan vocally, these idiots have a better chance of being acknowledged and validated. SJWs ultimately just want to be the most accepting the most woke the most open minded but more importantly the coolest and the most on trend and the closest to the popular kids. Pretty influencer trauma girl is cooler than some natives.
