I think "rape" is a bit of a hyperbole here. Yes, the cow is penetrated without consent, but the same is done all the time for rectal exams on all sorts of animals, including cows. Cows don't face trauma and PTSD and emotional harm from this penetration the same way humans do and to compare it to rape is ridiculous.
Conveniently left out the qualifier immediately following: "the same way humans do"
We absolutely know for a fact that animals don't experience trauma the same way and to the same severity as humans. They're literally incapable of human level emotional harm.
I am not denying that. I am saying it's not comparable to human trauma. This whole discussion is ridiculous because it hinges on the idea that artificial insemination is traumatic for animals when I would be really hard pressed to believe that when it's done correctly.
And yes I feel the same way about artificial insemination on dogs as I do on cows. It is a quick, instantaneous, and painless process that I cannot imagine any animal would think about twice when done properly.
