The 1st was dripping with vitriol and is what I have come to expect although it makes me sad. It used to anger me, and that anger caused be to have a post hidden in the religion forum. I have learned to restrain myself from posting there. I am surprised this thread was not locked for being in GD but then I am not in charge.
It is amazing to me the intolerance of some people who are liberal. The attitude of "my why or the highway" is anathema to the Democratic party as we are truly a big tent party. Some of the worrisome attitudes I have seen in my time on DU are extreme religious intolerance, candidate chauvinism, the inability for honest discussion on race, Israel/Palestine, guns and whatever. Then there is the suspicion of people who saw the light and moved to more liberal or progressive way of thinking.
I know that I have moved far afield from your original topic. That's me, I just fly off on tangents. I am like you, Catholic. I have attended a couple of Pow Wows and felt honored to be a guest at their sacred ways and would never have interfered either vocally or physically. We can learn from each other if we don't let ourselves become hide bound, stiff necked and obdurate. When it comes to the wonder of creation and the Creator it is prudent to just stand in awe of the mystery and feel joy in that you were given the gift of growing consciousness.
I don't think I answered your question but thank you for asking. May you and your inlaws days be blessed as you travel on the sacred way growing in peace and love.
