God didn't tell us to slaughter an animal any specific way. He only told us to not eat meat from animals that were... "strangled, and that which has been beaten to death, and that which has fallen from a height, and that which has been gored, and that which the wild animals have eaten from except what you managed to rescue, and what has been slaughtered on alters." (5:3) If you take 'halal' to mean meat other than those in the above verse, it is very unlikely that KFC and Subway are halal. If you search for 'KFC slaughter house' on youtube, you will see exactly how the animals are treated.
It will put you off. More.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
