We can live (with enough effort) in almost any environment on earth. We have travelled beyond the atmosphere of our planet. We are relatively beyond dying from many of the pathogens that killed us in the billions, in the past. We are able to prevent pregnancy, STD's, etc... that were common with sexual behavior.
Conservatives want "what is natural" well, go back to walking around naked in small packs hunting animals with fucking sharp sticks. Nothing since that time has been "Natural" every progress that humans have made with our technology, has been to live beyond the bounds of what other animals have to contend with. Our behavior may be a "natural" progression of our progress. Humans as physical animals, kind of suck, or teeth are not super sharp, our jaws can't crush bones, we can't easily lift 3 or more times our body weight, we can't run 60 miles per hour, our nails are fragile. etc... What we have going for us that has made us one of the more successful species on the planet is that WE ADAPT. We use our intelligence to make clothing, cars, houses, technology to enhance our ability to defend ourselves, to lift heavy objects, etc... We form complex societies for mutual aid and benefit.
Conservatives want CONTROL they want to dictate what people do and don't do. They are scared like children, except without being cute and innocent. They are ugly inside, always afraid and angry that the world is leaving them behind because they maintain antiquated notions on how we should live, because women want equal dignity and opportunity as men, because people of different skin color do not want to be seen as "less than", because people with different sexual attraction or whose gender experience and expression are different, don't want to be ostracized and killed. They are scared and angry that we moved beyond monarchy and aristocracy and are striving for systems that meet everyone's needs and give everyone a chance to develop their own passions beyond working from sunup to sundown so that owners can become wealthy.
Conservatives see a changing world and are SCARED and ANGRY where liberals and left leaning people may have some trepidation but we welcome the challenges of a new world because that is what HUMANS have always done.
