Earlier quoted context omitted.
What do you mean eating horses is not OK, in Switzerland we have plenty of horse butchers, you can find horse meat products like salami in all bigger supermarkets. Its not consumed in same amounts as beef for sure, but its not shunned by most. And yes there is no logical reason to eat beef (especially calves if we consider the cuteness factor) but not horses, horse meat is even healtier.
I'm not sure how "it's okay in !" is really relevant, TBH. There are plenty of places where it's not considered okay by a significant portion of the population, so it's a pretty valid to use it as an example of an inconsistency.
Your culture thinks eating horse is bad, other cultures it’s fine, but beef or pork is bad.
Even dog and cat are quite common in many countries.
