whatever man
if u go into molecular level
the protein u get from cow will be same as sungur, chiken , dog, horse , even human
y dont u start eating ?
there r certain norms for every culture
like eating dog may seem normal in some countries but for some country it is not
its same for us ... we dont consider eating cow as good ..........there may b not good expaination for not eating cow but that makes us different (at least for me )
i am not saying eating cow is bad .......... whole world eats
just  njoy ur steak .........
just dont make excuse that cow in nepal and cow in other countries are different
if u eat then y hesitate ........just say ya i eat cow ......
