Maybe. See, I'm the last person to pull out a "tone" argument; I've found that people who are willing to listen will listen regardless of tone, and those unwilling will find some excuse to dismiss any argument regardless of tone. That being said, I've noticed a lot of religious folks getting really turned off by the comparison, and it seems to be shutting down any possibility for conversation on this beyond that.

Now, whether that initial shock really shuts things down totally, or will result in them thinking more about it once that initial shock wears off, is another question I've heard raised.

And yea, I agree that the conversation has to be initiated. I'm just not sure of how best to go about that.
