My neighbor has ducks and they are indeed disgusting and charmingly cute. I've seen one get up to follow me for food and she was sitting in a large pile of her waste. Also duck rape is awful. Some have died from the duck gang rapes I was told :(
I think you do transfer too much! Lots of animals have a mating ritual that involves overpowering a mating partner. It’s not pleasant to look at, but then neither is watching a chimp rip an unborn fawn out of a deer, while the deer is still alive. Nature is nature and there are lots of situations where there is direct violence between males and females as part of mating:
Hyenas, where female hyenas are larger than males, necessitating them to submit to female dominance during mating.
Many species of spiders and praying mantis where the female eats the male after mating.
Antelopes, where males often overpower females before mating.
Dolphins, where groups of males isolate females using herding techniques.
Hermaphrodite slugs where one partner will eat the penis of the other partner to prevent it mating further afterwards.
