I know what you mean about how the responses can make you sad. It's disconcerting to see how many people are so wrapped up around utter bullshit. I also wonder why they're so afraid of anyone questioning what they believe that they have to deny that we even exist. Their "argument" that it "takes more faith" to believe in the big bang or evolution than it does to believe in Jesus, THEREFORE there are no true atheists is just pathetic. It's not all, "Oh these poor victims of bad programming" though. I'm reading a pretty disturbing book titled Religious Right - the Greatest Threat to Democracy by A.F. Alexander. There are tons of unscrupulous people out there raising billions of dollars and stealthily plotting to install old testament law that wouldn't be all that different from sharia law. If we don't collectively watch it, the dark ages could be back with a vengeance.
It's about which pays off for people, making (such as planting or throwing a pot) or taking (such as taking another person's cropsor pots) by force. Once weapons technology became so efficient, with metal blades, those who were physically stronger (men) and willing to dominate by force were reinforced. The flip side of the technology/human culture coevolution is that Dominator culture is now destroying the planet permanently. We're taking and taking from nature, without regard to natural limits. So Partnership Culture is likely to be the only kind of culture which supports long term sustainability on Earth. Taking was a short range optimum but it's not a long range optimum for a species utilizing all of a planet's resources. My impression is that you're focused on blame rather than stepping back to see how humanity has been molded by technology.
The UU church you visited was most likely First UU of Austin on Grover Ave. -- I've visited there myself. It is a very nice church. The majority of UU's are Humanists. So I fit in very well. I like the UU principals.
The nudist camp you are speaking of is Hippy Hollow. I never been there -- but I have heard of it. I think the lake you went canoeing on is Town Lake -- they just renamed it Lady Bird Lake.
