It fascinates me that people who very much eat meat are often various levels of uncomfortable or weirded out by animal products not made of meat, like tripe or what goes into a sausage or whatever.
My friend, you already eat chunks of a carcass. You already gave up on the notion of avoiding the ickiness. How is a leg inherently less upsetting to eat than a stomach. If you eat dairy, you eat basically spoilt milk. And milk itself comes from modified sweat glands.
If you want to go vegetarian or vegan, good! Eating meat is unethical and has its own health issues, and also it's bad for the environment. If you don't, fine. Get off your high horse and enjoy the horse meat.
I consciously try to reduce meat in my diet and am considering going vegetarian. But because of ethical and environmental concerns, not because of arbitrary, cultural notions of what is gross.
