Certainly there are cruel ways of producing veal, but the industry is improving for a variety of reasons tho it certainly has room to improve. Keeping in mind that for the calves mainly used to make veal, male calves from dairy cattle breeds, if veal were banned or no longer economically viable, they'd by and large be killed shortly after birth. There's no economic reason for them to be raised for beef. Hence no one should be under the illusion that ending the human practice of veal consumption would allow male dairy calves to grow to adulthood.
So the question is: can veal be produced in a non-cruel manner and still be economically viable?
I support banning veal crates and veal tethering. I don't know enough to know whether milk-fed-only veal should be banned. But I see no reason to ban veal in all its forms.
The malnourishment and stunted physical development is what gives the veal its unique flavor. (I have never eaten veal myself, just quoting from the sources.) If you ban crates or tethering
and require proper nutrition, the calf will be less valuable (maybe slightly more so than regular beef, if that) because the cruelty is literally what gives the veal its taste. But if you support banning cruelty against baby cows, you support banning veal.
