A question for NickW or anyone else who loves God and his fictional existance:
In the Bible, who killed more - God or Satan?
Humans were created to live forever. But Satan tempted the first humans to disobey God resulting in God's rightful anger. As a result we live in a fallen world in which we all deserve death, ie the default and rightful state is for me to live a limited period and therefore die. God could have left it like that but "God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life." [John 3:16] Judgement has been carried out by God both before and after Jesus died and rose again, which I presume are the deaths you're talking about, and one day all of us will face judgement. But those who accept the free gift of mercy from God will not be judged for who they are, but for who Jesus was.
Does Christianity still see homosexual individuals as essentially evil?
Echoing what Oswyntail said, some people who falsely claim to be Christians also falsely suggest that somehow all heterosexuals are completely good and all homosexuals are completely evil. The bible has the following to say:
There is no one righteous, not even one;
11 there is no one who understands;
there is no one who seeks God.
12 All have turned away,
they have together become worthless;
there is no one who does good,
not even one. [Romans 3]
It does in stauncly Catholic often African Countries.
The best thing to do is to check what a "Christian" says against the bible, because what they and the bible say is often miles apart. A good question to ask is "where did you get that from the bible?".
What annoys me is the outdated rubbish that is still being preached by mainstream religion, despite the social and scientific advances made in recent times
Many such scientific developments were of course made by Christians, suggesting that the two can co-exist very well. I'm not sure what you mean by social advances. If you read the bible, you will discover that even in Old Testament there were all the hallmarks of today's society - gardens, jewellery, drinking, women in high profile positions (gender equality is a biblical truth, not something that's existing in the last few decades), sewage systems, water supplies, sexual liberty. There's no mention of democracy but we know it was around in that time.
