There are definitely some members whose opinions I believe to be more credible -- rather consistently. There are also other members whose opinions I find less credible -- consistently, as well.
IMO credibility involves -- open-minded, reasonableness, honesty, fair tactics, willingness to allow others to disagree with dignity, etc.
I regularly read posts that I disagree with, yet still find the opposing opinion credible.
It someone takes a position that they must annhialate opposition by any means -- I figure they are not confident that an honest search for the truth will reveal workable solutions. I, therefore, may doubt their honesty -- and credibility.
That's fine.
Mockery isn't used to annihilate opposing positions, btw.
It lightens the mood with laughter and wit while calling out an idea that is unrealistic, or repressive, or oppressive, or archaic.
A parent at a PTO meeting demands her children receives education that does not conflict with the Dragonriders of Pern. She holds her position with quiet dignity, but maintains that Bible followers and monotheists are destroying the school system and future generations of humans. After hours of serious debate about how Dragonriders of Pern is not a science book and should only belong in literature class, somebody cracks a joke about her position that ends the discussion and allows the meeting to move on to more relevent topics.
The woman feels hurt by the group.
She took hours away from the group to argue her wildly unrealistic world view.
Serious discussion and attempting to give her pov attention took valuable time. She is clearly delusional.
Mockery, in spite of her feeling bad as a result, moved the discussion to more realistic action items.
I think the focus is so much on trying to equate compassion with patronizing every single worldview, including Zeus believers, people who cry "Armageddon", "Planet X", or the moon-landing hoax, or people who think women should not be given the right to vote. I don't take these positions seriously.
They make me giggle.
And I'm being told I'm a big huge meanie head for it. That makes me giggle too. Life is too short, ya know.
