Do I need to start protesting about female lions doing all the 'wifework' whilst the males strut around at home?
No, male poachers are already taking care of that problem. They mostly kill the male lions because they look more impressive.
What shining examples of feminist allies they are!
There’s also lots of interesting research done about Male violence and abattoirs, so basically there is more domestic violence in towns where there are slaughterhouses. This is true even if you allow for economic factors.
That's quite interesting, but not unique to feminism.
Some male thinkers have also proposed that cruelty to animals should be outlawed, not because the animals suffer, but because anyone who is cruel to animals will soon be cruel to humans, too.
It is an interesting theory, and I am inclined to listen to Carol Adams, but I am allergic to the "if you don't include XY, your feminism is no true feminism at all" argument.
Feminism is true feminism if it aims to liberate women from patriarchy.
