Even our slaughtering the goat is in order to distribute its meat among the needy as well so it is done in charitable intent. Of course with regarding it been "murder" "inhuman" etc then that will be the age old "vegetarian" vs "non vegetarian" argument that can go on forever.
That said your idea on giving money to the needy in the horn of Africa is excellent. Specially since this is the month of Zakath as well, that's one area that needs as much charity as they can get.So thanks a lot for your suggestion.
And to the you, O Muslims: remember always, we cannot get all abusive and angry when someone questions us on our faith. This was not the way of our Prophet,peace be upon him. You have to answer them with patience and have a great deal of tolerance. This is by far a great obligation upon us.May Allah guide us all and set us upon the straight path always...Barakhallah feekum, Aameen!
