So, there is animal rights, and animal welfare. I think one of the main problems for orcas is size. Creating an appropriately sized habitat for them would be a gargantuan endeavor, however, if we could, i think a lot of us would be less vehemently opposed to keeping them in captivity. For pigs, this is entirely plausible. While i'm also very opposed to our current factory farming practices, since i'm fairly nihilisti…
It sounds like you support animal welfare, but not animal rights. I would expect someone who supports animal rights to not be OK with captivity for human gain.
I try to take a more game-theoretic approach. Support those that are doing more to change the culture of how we treat animals to minimize the harm that exists and will persist. This may even arguably go as far is purchasing potentially objectionable animal products from those that are trying to change the social norms of farming.
The animal rights argument is perfectly good to have in the halls of academia, but in the world we live in, those of us who are good consequentialists may vastly differ in our approaches to how we should respond to the marketplace we live in to most effectively reduce the suffering that persists. It's also arguable that a diversity of approaches will be more effective due to the vast open-ended questions of how approaches will be accepted by the greater population. I for one think that convincing people that we should raise our "bacon" humanely will do vastly more for the reduction of suffering in the world than would telling people we should ban it because it's clearly immoral to consume.
