Since you mentioned the name, I did notice quite obviously the disrespect everyone had toward Kamala Harris in the news and online comments simply due what they called her.
Almost everywhere, it was quite common for people to refer to her as Kamala and not Harris.
I suspect it was either due to her being a woman, or due to her being Indian (Kamala sounds a lot more foreign than Harris).
It was always "Kamala vs Trump" never Harris vs Trump or Kamala vs Donald.
I agree, even if Biden was 20 years younger I think he would have won. If he was 20 years younger and female and Indian he would have lost just as Harris did.
It was definitely policy that hindered them, but also the sexism and racism.
