I agree that all of these points played a role. I really do.
But I also feel this isn't the silver bullet. I really think much of America's indifference to racism, sexism and hatred played an even bigger role.
An autopsy will be done from many circles. Yes, I think genocide was ignored. But much of white America sweep so many other things under the rug as well--including the fact that Trump is the most mediocre white man to ever win the presidency and most often country is OK with this.
White supremacy prevailed. Most of the country WANT Trump. This is bigger than Kamala or Democratic strategy. This is inconvenient to hear, but we need to sit with this.
This is what happens when you undermine core values, when praising Cheney seems more strategic than respecting your base. This is when you treat genocide like something to sweep under the rug, believing ignoring it leads to the presidency.
