There are lots of topics and discussions where, ultimately, my answer is, "I don't know (am not certain), but this perspective works best for me right now." There are many things where I believe my understanding will change over time, as I am exposed to more outlooks, have various experiences, contemplate more deeply and receive greater light and knowledge.
For that reason, the last thing I want to do is shatter someone else's "working perspective" by insisting they see things my way, because:
1) they actually might be right (as much as I might doubt it at the moment);
2) they might be seeing things exactly as they need to see them in order to cope best;
3) they might not be able to see things my way at the moment, even if I am correct.
I see my responsibility as modeling acceptance of different perspectives - simply because I believe it is the right thing to do and because I want them to accept my different perspective. I can't hold them to a standard I myself can't live.
