What do I say?

They've come back with "You say I have no grounds for believing in God: a great force that cannot be understood. However, scientists have long ago admitted that the laws of science that we observe today have been altered/violated by a great force which we do not understand. In fact the 2nd law of thermo proves that this force exists/has existed."

I have no idea what they're on about when they talk about this "great force". They honestly seem to think they're scientifically on the right lines, which worries me. Considering their statement is so vague, I've given up trying to refute it.

When was that? Ancient Greece?

That is what we call a good old fashioned manipulation of the truth to suit their argument.

Also known as a LIE.

Jehovahs Witnesses were trained – brainwashed – for years to counter argument X with biblical quote Y.

Which is why you tell them that their fucking bible is a load of primitive shit and not worth the paper it is written on.

They do not handle outright scorn very well.

They do not handle outright scorn very well.

I prefer a more subtle approach. No need to descend to their intellectual and moral levels.
