Peace is not achieved by all believing the same thing (even if that same thing is achieved through engaged debate). Peace is achieved by learning how to listen (not agree) or by not wanting what someone else has.
In the case of a debate for example, what someone want's most (I assert) is to be heard. It isn't to be believed, but for their words, their thoughts, their feelings, their... "them" to have mattered to someone else. This concept is often stated (not entirely accurately, at least as it is formally defined) as "respect."
In the case of wars on the other hand, what almost always matters is not what someone says, but the resources they possess. This of course doesn't count when wars are started by butt-hurt rulers that happened generally because they felt they weren't heard (i.e. respected). In that case it becomes a "war" because of a misapplication of the concept of sovereignty. That's a whole other can of worms.
Is that a need? Is it even desirable?

Dear Lady, yes a common denominator is required. We have to assert it together.
I don't think I understand what you mean by "common denominator." Do you mean "the ability to speak to each other?"
If you mean we need the ability to speak to each other, I have no idea how you are relating that to a forced path of learning (curriculum).
