What I've run into in my deepest arguments is that I've found that people have had a hard time understanding what I meant. And so then I've been thrown back on myself and how inadequate I am as an educator and communicator. And then I've given thought to how best to educate or communicate. And then I've concluded that my time is better spent being creative. Debating takes energy away from being creative. This goes for the debates about which I care the most.
And then there are other reasons why people are not persuaded. Maybe they understand but they find it impractical. So then maybe energy is better spent problem-solving than debating.
What does debate accomplish? (Even though I like to debate and to follow debates, and I often learn from debates. Okay, maybe debate can lead sometimes to education and persuasion.)
