That doesn't seem like a reasonable belief (without source) for two reasons:

1 - AFAIK, the natural process doesn't favor milk production above all else

2 - There has to be a reason artificial insemination is used. It _might_ be for higher veal production, as you imply, but I always thought this was a secondary aspect of the milk industry.

Also, in your original point, you argued that "there is no rape involved, if is artificial inseminated then it is a medical procedure".

If you want to argue that applying terms like "murder", "cruelty" and "rape" to animal husbandry isn't legitimate, fine. But let's be clear, medical procedures _have_ been used [probably since the beginning of medical history] to rape.
