Yes, louder!

Someone elsewhere in this thread is suggesting that we're all obstinate and inherently resistant to change, but ... I can't relate.

The ability to learn from our missteps and prejudices, and subsequently change and grow, is a hallmark of being human. It's not about education, either. I've known people who only went through grade 3 who are not so destructively stubborn. It doesn't seem like any way to live to tear other people down because I encounter something new to me.
