Another point: in the US, historically, horse-meat was used in canned dog-foods. While we love our dogs, we don't really want to eat the stuff they will eat. (This is changing, canned glop is fading in favor of kibble, and junk-kibble is being replaced by gourmet kibble with highly detailed ingredients. I'd eat my dog's Chicken & Brown Rice, but it's crunchy for my teeth and fatty for my liver.)
The USA is not 100% anti-horse-meat. Many Italian-descent folks ate horse in the old country and maybe would today, but it wasn't available (in good quality) so it fell out of habit. In my youth a butcher started to offer it. A small but very loud group of picketers forced him to stop.
> I suppose bear meat is ok?
Bear is rare.
People in US do eat bear. Apparently common through mid-century. Hunters take California bears for meat (they are too small for rugs). http://www.theatlantic.com/health/archive/2010/11/bear-a-meat-worth-trying/67024/
Wild-beast meat in general is rare. I have had elk, and seen boar, but I understand those are grown on farms.
While there are hundreds of bears in cages, they don't seem to be sold-off as meat. Among other things, elk or boar can eat plants, bears need some meat or fish. Carnivores are just too expensive to be food. I doubt there is any commercial supplier for bear meat.
Also, bears accumulate trichinosis. This killed one of the Arctic expeditions who were eating polar bears. http://www.mcclatchydc.com/2012/10/26/172668/meal-of-black-bear-meat-leads.html
One wild meat that you can get many places: venison, deer-meat. In New Jersey you could just peel deer off the road (or the bottom of your car). In season you could often find a hunter and sometimes get a piece; or go in the woods and bag your own. Here in Maine, they think they should have deer, but mostly don't. Deer were common early/mid 20th century when farms were being abandoned. Once the woods grow back, deer can't thrive. They do much better in suburban gardens, such as most of NJ and some residences just outside the national park. (Coyotes are a very minor factor: deer can out-breed the coyotes.)
Maine still has Moose. Enough so car-moose accidents are somewhat common (and very serious: a moose is so high the body hits above the car hood). Common enough to harvest a few hundred a year (lottery). I've had moose. It is about the only wild meat I'd eat more than a few times.
