It's funny because the premeditated victim instead turned the tables.
Yes, if it was man on woman, we'd be crying out for bloody murder, because biologically, men are stronger than women and men overpowering women is a lot more common than vice versa.
It's like this: if a man hits a woman, he's looked down upon for hitting a girl. But if a woman beats up a man, it's viewed as humiliation for the man, and perhaps rightfully so.
But yeah, in Russia, hot girl rapes you!
I mean come on the reason it's funny is that it's so completely out of this world and it's karmic justice It's like a robber trying to rob a house, falling through the roof, landing on a butcher's knife with the blade facing up, and getting his foot cut off (unfortunately in reality something like this happened, and the would be robber sued and actually got a settlement

. Hopefully the castle law covers this).
What's interesting is that in the U.S., if this guy tried this and simply got shot dead, that'd be the castle law and she'd get off completely free.
