in torture, the pain is the point. while i think factory farming is too ambivalent about suffering, i also believe the suffering is only incidental, not intentional. it's not torture.
perhaps you could explain that subtle difference to the animals going through the system of abuse.
Im sure it would brighten up their days no end to realise the pain they are experiencing is not the point of the system and that therefore, they are not being tortured.
this is just posturing and rhetoric. i have no problem with most forms of exploitation (this is true of most people i think). my problem is unfair, or even non-consensual, exploitation of other people.
