Not exactly sure what you're trying to get at. Something about abortion?
What you've been kept from understanding all your life is that all milk comes from a mother. To milk a cow, first you have to get her pregnant. She'll provide milk for about a year, and you have to get her pregnant again. A dairy produces hundreds or thousands of calves a year that they have no use for. They go often into veal because a farmer would get a better return from a breed specialized for producing meat rather than milk. So an inevitable side effect of buying milk at the supermarket is murdering a bunch of babies.
"Installing" is also a made up term. We made up both those terms because they are useful for describing distinct things that exist in our lives. "Side loading" further specifies "installing". I really don't get why this is so controversial to a certain segment and I suspect I'm just not that kind of autistic.
