We have all the evidence we need to show that they don't mean what they say and they insist they know better than we do what we say means.

Some here find parsing of the language tedious. But truly, what fun it is.

We have all the evidence,
[that] we need[,] to show that they don't mean what they say
and they insist [that] they know better than we do
what [that, which] we say[,] means.

Take that, "doctor".
