All we can do is try to understand as much as we can, and be able to understand the opinions of others. I am not suggesting that we all make sure we agree on everything. We need to acknowlege the fact that that is fundamentally impossible. We have to learn that there are other ideas out in the world that cnanot and need not be changed. All iseas are valid.
All concepts deserve a chance.
There should be no value other than a personal value to influence ONLY personal decisions. As long as you know why, then you understand.
