Yeah they dont really hold up lol. It takes specific ways of looking at things for yin and yang to work. When that happens they’re great. When it doesnt… well, we get discussions.
Yang from the viewpoint of chaos and growth works. Yin as well with order and constriction. Yang being the light causes good to be included and so yin as darkness/shadow gets evil. Going too far with it has easily seen problems.
Similar ideas are seen within element theories. Fire vs water ends up getting some of its difficulties fixed with air, earth and spirit (if going the 5 element route).
All paradigms have pros and cons. Sadly people get weirded out and upset by the cons more than appreciating the pros and taking the cons in stride. This ends up going into the realm of my frustrations with dogma
