I just simply feel that everyone is free to their opinion without others having to find a way to marginalize it/them. To be quite fair, I feel we all have "valid opinions" daily in the real world (that we've not experienced) on work, politics, presidents, places, foods, procedures, lifestyles, etc and that it is ok to have diversity in opinions without having to meet any sort of criteria to have ones opinion to be "valid", or to experience it, to answer the question posed here. I feel we should all listen more and marginalize each other less, here on this planet. There is room for everyone and their opinions regardless, imo. They are merely "opinions". One can easily disagree with an "opinion" without having to find a way to disqualify the person or the opposing view one might hold. But yes, I feel it would be nice for people to express their varying views cordially. I am all for varying views and having diversity and encouraging dialogue. One of the ways we can encourage good communication is by not needing to feel we need to "label" people's views/opinions, which are important/personal to them for whatever reason. If one does have experience of some sort with the topic, this may indeed lead to a deeper opinion of sorts, yet the two parties may (and often do) still disagree and this is all ok! In my view, the importance is in having the honest dialogue where neither party is made to feel like their "opinion" is inferior.
