When the mormon missionaries have come to my house harrassing me and bashing my faith in Jesus, they have usually brought nothing but acidic bigoted arguments against the Christian Jesus, and pushed the muddy belief that the Mohammad-like Joey Smith is their savior...
I invite them in for dinner. They are always hungry and I have 2 hour captive witnessing audience. When they start in with their canned ‘testimony’, I just counter with mine which is NOT canned.
