Muslims are a minority in India. They should have a way to distinguish themselves from their non-Muslim fellows, should they so wish. They aren't hurting any people - yet I don't know the importance of cows in the hindu religion; are they the equal of people or are they animals or are they supposed to be sacred somehow?
If sacred or the equivalent of people, the Muslim choice of cow vs. others strikes me as vindictive; nevertheless, I think force should not be used to stop them; rather inform your Muslim neighbors politely of how you feel well in advance and only if they then choose to continue cow slaughter point out to your family and fellows that Muslims are behaving this way out of wickedness, not necessity.
