I think you've lost track of the difference between other people and yourself. The words you're using seem to talk about how other people feel, but you're actually talking about how you feel and assuming that any difference between the two is rooted in ignorance.

> "your kids’ reaction"

Maybe this should be "my reaction as a kid", since you don't know that person's kids.

> "The emotions one feels"

Should be "the emotions I feel"

> "If people had to see their livestock suffer, they would make a different calculation"

Should probably be "seeing it changed how I feel".

People are more than the sum of our experiences, two people raised in the same environment with the same kind of experiences can have completely divergent values. Therefore it's wrong to assume that people would share your values if they had your experiences. In the case of meat eating particularly this should be obvious; the reality is that most people exposed to the industry, either for the first time as adults or as kids, don't turn vegetarian.
