I can hear those conversations: "Did ya know that the Pastor's wife has pet frogs and carnivorous plants? Better keep the kids away from her She's weird!" or "Don't eat the cookies... they're laced with insects." or "If ya don't behave, I'm going to send you over to the parsonage, where she has plants that can eat you!"
But they can be won over... eventually. I gave a capensis to the church secretary and now I get to borrow her camera. I showed our Pastor's wife the minibogs a few weeks ago and one hre sons the butterworts and bladderworts. These things must be introduced slowly and in a positive, non-threatening light.
