I'm not comfortable watching people be killed, but I'll celebrate American Independence Day.
I'm not comfortable with watching surgery, but I'll undergo surgery.
There are loads of things I benefit from that I don't enjoy watching.
EDIT: FYI, I have butchered pigs, chickens, and rabbits.
I am not comfortable watching women give birth, that doesn't mean I shouldn't have children.
If you're not comfortable watching a woman give birth, you can choose to avoid the many thousands of available videos. You don't have that option with factory farming methods.
Nobody wants to watch animals being slaughtered on an assembly line, but they should absolutely have the option to see what happens with their food. I don't think there's any moral room for "It would be disgusting and probably harm their business, so we shouldn't film it."
