I think we ALL get defensive when we're accused of something we didn't do! I certainly do! And maybe sometimes I get TOO defensive, which as you say, makes me seem guilty, but I HATE being falsely accused!! And like you, I'll defend others who are falsely accused too -- I don't see anything wrong with that. I think any good friend or ally would do that.

I hate conflict/confrontation of any kind so it seems funny that I'd get defensive and/or defend others. If there's any kind of 'fight' going on, I'm the first to run! It comes from my childhood, when my parents would physically fight, and it terrifies me. So it sounds like I'm saying one thing but doing another. But I DO defend people, and I do get defensive if I'm falsely accused. Go figure.
