You previously say people could keep their own beliefs, now you say their own beliefs conflict with the beliefs you ask them to accept, can they keep their own beliefs or not?
Many different version of religions' Gods say every non-believer will go to hell and command their followers to preach his words/moral/law to the world, many of those Gods' words/moral/law contribute to the barriers you're talking about, please ask those Gods/believers stop making barriers already.
Oh no, some or many of them say they're helping people to avoid hell and they'll not stop preaching until the end of the day that their Gods comes to earth to bring them to heavens, so you ask when'll the peace comes...?
When the Gods comes then there might be peace...
If the Gods doesn't come, who'll know when will peace comes once and for all...
In the mean time, some people continue to live their live.
Some people continue to wonder when will the peace come.
Some people will make their effort to bring peace into the world.
Whew, some people's peace is that when everyone only eats apple then they'll be have peace of mind. Because their religion's god told them people who continue to eat apple will go to hell.
While majority of people have no problem if anyone wish to eat fruits other than apple because their god haven't told them so or they're atheist.
What an odd version of peace it is.
Who say peace is only up to politicians?
