Athiesm is a cancer, the quicker we kill it, the better society will be. In other words, Athiesm does a lot of bad by being propagated.
Listen to yourself. You’re no better than an Islamic terrorist wanting to slaughter infidels.
You need to learn to distinguish between belief and people holding that belief, but maybe you are getting that wrong on purpose.
No. I’m thinking logically. The only way to kill the belief would be to kill the people who hold it.
Have you heard of the concept of changing your mind or even changing your world view? Or even just the concept of preventing the people who currently hold the belief from passing it on to the next generation?
