Quora is useless and so is Google, but the other two are hate because of trauma.
The people whose villages were pillaged by the Red Army, who raped all women there and stole everything of value will likely hate Russians.
Women who experience a lot of violence from men, even second hand, will likely hate men. It’s normal, hate is a natural response to harm.
Doesn’t mean all Russians are bad, or all men. I don’t feel personally attacked.
People who experience violence from <race> might well feel hatred for <race>. That doesn't mean that when they state "I hate <race>" they are not being racist.
You can make up all sorts of excuses for racism and sexism and all the other -isms. They don't make it right.
TL;DR: The Guardian is misandrist.
Yes, if you apply this logic, you'll reach this conclusion. I don't think this is equivalent to racism though. The latter is rooted in violence against the hated, not the violence of the hated.
The problematic racism is when people hate <race> despite <race> never harming them in any way, usually because that helps them justify systemically disadvantaging <race>.
You don't make the distinction, and draw equivalence between the two, so for you it's equally bad, I understand that.
