hi..
pls dont get me wrong.. but im not supporting any religion here.. Tamil people think the bull is there sacred god, but still they eat meat (not all, but there r some tamil people who eat beef) Buddhist people also eat meat like beef (atleast 50% majority) other than eating meat, the cows leather is a highly essential item for the rabanas, or sacred scriptures, this is indeed a must because without the speciality of the cows skin the prominent sound cannot be altered. Christians also do some sort of sacrifice in terms of like hajj but in more festive festivals. The muslims obviously give tender that they should sacrifice to feed the needy, This type of sacrification shows that the Animal wouldnt get hurt since they are cutting where the brain connects on its throat, But then again under some circumstance people will be disgusted as they sacrifice in mass quantities of these animals, So any animal lover would feel disgusted.
So eventhrough the muslims do sacrifice, There are other religions who take note of this sacrification to help themselves in return.
