Sorry to disagree with you (no change there then

) OB, but "a little bit drastic" is not what I'd call that.
The way that family has been treated by some (not all) of the campaigners/activists is nothing short of
criminal.
To me it's utterly hypocritical to treat fellow human beings in a worse way than the treatment they claim is being given to the animals in their care.
I am fully behind anyone that wants to treat animals properly, but when there are people in our world dying of starvation or suffering in other very preventable ways, you have to wonder what kind of twisted individual spends
all their waking hours doing something like this instead of helping their fellow man. (I'm not saying it's a worthless pursuit, I'm just pointing out the seemingly misguided priorities)
I don't know first hand, the conditions or treatment of the guinea pigs at this farm. But I doubt very much that they're being treated like the family that own them.
