Thanks for understanding and being willing to entertain a different perspective! I'm glad I could help.
Whenever I catch myself wanting to call someone or their actions stupid, I consider whether telling a 5 year old child that they're stupid has ever helped them learn (good) lessons, and whether calling them stupid is a better teaching strategy than rewarding positive behavior. Research suggests that killing someone's self esteem isn't great for learning, especially pro-social behaviors, so it's probably also not a great first choice for whatever situation I've run into.
