Something's weird with this; I have heard absolutely nothing about this.
Surely this is botted? Social media platforms don't take off like this. Regardless of if its legit or not; who is funding this? No social media platform ever makes a profit.
You are grouping all indigenous people together by saying "denying the existence of issues they care about and talking over them" I emplore you, who is "they"? Are you implying that all native Americans hold the same beliefs? That they are the same people? I also never claimed to represent native Americans. I would never speak for a culture or peoples I don't belong to.
"Cultural apropration" is a nothing burger championed by people who often have no ties to the culture that they claim needs their protecting. A white man speaking for indigenous american culture does not give indigenous americans more of a voice, it takes their voice away by revoking their ability to speak for themselves.
Awesome, blatanly obvious misinformation.
