In my opinion to speak about cruelty to animals is a controversial topic.For this exist an wide range of opinions.The most strict people as vegetarians, always give some reasons to no eat meat from animals ,meat ,fish and by-product of them.
the procedures to sacrifice animals are very cruel ,therefore they refuse them.
The defensors think this idea is incorrect because people need to feed,the human is omnivoro and he can eat everything.
In another hand the cruelty to animals means to sacrifice animals in parties,per example in the Spanish bullfight.Some people think this is art some people think this is a slaughter.
But the bullfight atracct a lot of money,business and tourist and the managers think if the bullfigh should be forbidden nobody should eat meat neither.
personally I'am vegetarian and I don't have problem,but sometimes I think if the vegetable and fruits will be suffering a cause of this either.
