No sense!
If GCD is a lier, then you cannot believe what they said?
Is this your logic?
But the point the post made is not from GCD, it just happens to be the same as GCD's point.
An example: 1,I say :"1+1=2"
2,GCD say "1+1=2"
3,GCD is a lier-->what they said is wrong
4,what I said is wrong-->1+1=\=2
