If God loves everyone, why do Christians hate particular categories of people, e.g Homosexuals. Shouldn't they follow God's example?

Yes. http://www.catholic.org/news/hf/faith/st... Francis explained himself, "The Lord created us in His image and likeness, and we are the image of the Lord, and He does good and all of us have this commandment at heart, do good and do not do evil. All of us.

'But, Father, this is not Catholic! He cannot do good.' Yes, he can... "The Lord has redeemed all of us, all of us, with the Blood of Christ, all of us, not just Catholics. Everyone!

'Father, the atheists?' Even the atheists. Everyone!" We must meet one another doing good.

'But I don't believe, Father, I am an atheist!' But do good: we will meet one another there.

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.
