You can banish one thing, or person, or idea from the world. But only one, what or who would you go for.
Please think about it as widely as possible, but also be specific if you can. No point in posting that you would banish hate, wouldn't we all.
Don't make it a person from this forum either - it's too obvious.
Mine would be Racial Intolerance.
I despise the idea that people should be judged by others, simply because of their racial background. Don't like someone if that's how you feel about that person, but do it for a reason not just because of his / her race.
