Its anything but personal and it should be discussed at length whenever possible where ever possible.
The worst thing we as a society can do, is continue this idea that one should not discuss one's ideals. That's why we have so many ignorant people who find comfort in silos. They have never developed the skills necessary to think past their beliefs.
BTW: that's what a liberal education is all about. Challenging your ideals and pushing your intellectual limits. And that's a great thing for people and for humanity. Insularity breeds crazy. Always.
