From watching interactions on an email list (not one of ours 🙂 ), I offer this: the line between “stating your truth” and “getting defensive” gets crossed when you stop having fun and start getting annoyed. And just because someone disagrees and isn’t willing to debate an issue, doesn’t necessarily mean they are getting defensive. Maybe they just like talking about what they believe. 🙂 But only you know if you’re still really having fun or if you’re trying to ignore a nagging feeling of needing to prove something.
