I assume everyone here is vegan? Or eats only meat, dairy and fish that comes from extremely high welfare sources (i.e. rearing the animals yourselves so you know what's going on).
Factory farming, animal testing and other forms of animal cruelty for human use is FAR FAR worse than fox hunting in my opinion. Save your efforts for more worthwhile causes.
Foxes have a life of freedom, then are chased, as they would be if they had any other natural predator. Just as e.g. mice or rabbits are chased by birds, foxes, cats, dogs, badgers etc. Chasing and tearing apart are just a part of nature.
Keeping animals locked away inside for their entire lives, having their babies taken away from them at birth (or very young) and dying in the horrific environments of slaughter houses is absolutely barbaric in my opinion.
Female horses stand their whole lives on concrete flooring having their urine collected, having yearly foals, to collect the hormones for HRT. This is barbaric.
Beagles that don't get to go outside their whole lives. Monkeys whose young are taken away so they can test their distress for mental health research. This is barbaric.
Fox hunting is not barbaric. In my opinion.
(disclaimer, I am not a fox hunter and never have been. I wouldn't choose to do it, but I don't think it should be banned. I think intensive factory farming should be.)
