You brought this up, not me.
> 1) the scale of suffering is obviously far far greater than family-scale slaughter
Not if every family has to slaughter their own meat, the scale is the same just distributed so you don't see it.
> 2) the way in which we do factory farming reflects poorly on us as a species
This isn't inherent to factory farming though, just the ways it is done in some places. And this goes for family farming as well, some families would put animals in small cages and not take care of them to save money and because they are lazy. If you filmed them and their animals I don't think people would feel any different.
