Tell them that you considered turning the name over to them, but if you do that they are acting like a business, especially with the trademarks, lawyers and such. That means they'll lose their tax-exempt status with the IRS, and you're required to report that. You'd feel real bad if the IRS made them pay taxes, and of course they could spent a few hundred thousand to fight it. So tell them to got ahead and tell you how much damage was done to their BUSINESS, so you can forward that on over to the IRS and get the ball rolling.
Or, if they're really jerks, they're obviously not following their "bible", so go ahead and redirect the traffic to a hardcore porn site.
