Actually, almost all of those would be true if everyone lived according to Christian principles.
I agree.

The only exception would be the slaughter of animals, but we'd only kill to eat, and we'd do it humanely.
I believe in Heaven we will still be able to eat what we like - like KFC - but without the killing. Don't ask me how but with GOD all things are possible!

That's figurative language to prophesy that enemies will learn to trust each other and eventually to love each other and stop being enemies.
How do you know it's figurative?

NO. Firstly, mosquitoes are NOT GOD's creatures. They are Satan's creatures. Secondly, why should I allow a dirty filthy parasite to feast on me? Do you have any idea of how many germs and diseases mosquitoes carry?
