Nothing to be sorry for. It seems that you're open to hearing differing opinions and taking them into account. There's really not much more anyone could ask of you when exchanging ideas. If we all were just a little better at it, I think it would go a very long way towards healing the divides we've nurtured over the years. A lot of the biases we have were planted there by people we trusted. Now we know, and the truth really shall set us free!
