So with mh17, russia found this witness who they gave a lie detector test to. And this shill is like "OMG these noobs no one uses lie detector tests they prove nothing".
It really gives me the shits how the shills do that. They basically use the "throw the baby out with the bathwater" trick. The emphatically insist that something tangentially related is untrue and imply the rest is false.
What's the solution to this?
I don't really have one but a good counter tactic is to ask them "Why do you think lie detector tests prove nothing". Often they can't justify their points and then you get the upper hand.
