I didn't say because it sounded nice, I said because it sounded logical and the best thing to do. That didn't mean people had to change their ideals for another, no. But if more people used their heads and listened to other people rather than getting into the one-sided "I'm right, you're wrong" mindset, then we would live in a much much better place.
Think about it like this:
"Hey, I hate you because your religion is not my religion, I shall now start a war with you"
"But sir, we are a peaceful nation, and our religion isn't all that different from yours, we may believe in a different god, but isn't it all really about what that god teaches us?"
"Oh. I suppose you're right. I don't agree with your religion per say, but I understand your views for supporting it, I will now leave you at peace."
If the world worked like that and people weren't closed minded, then it would be a much better place.
Also, did you just say socialism was a good thing?
