Where does lying by omission begin and slant end?

Dr McHugh, former advisor to the Vatican on sexual matters, is an expert in the field of addiction. He's never actually treated a case of GID.

Moreover, his views were published in a religious journal, not a medical one. They're quoted often, because he's almost the only one espousing such views. To say they are "on the fringe' is an understatement.

It's true that Johns Hopkins no longer provides surgical treatment. Their surgeon left, so they now refer patients with GID elsewhere for surgery. They closed down that section over 25 years ago, before 1980, when Dr McHugh was last involved.

Some quotes from a real expert on the issue:
"Q. Dr. Cole, does the fact that a condition is listed in the DSM
mean that it necessarily has a purely mental or
psychological cause?
A. Absolutely not. It's listed in the DSM because it
has to do with the mind, with the brain, with
emotional suffering. I mean, you also have learning
disabilities in there.
You have, you know, people who have sexual
problems, a man with erection problems, a woman
with orgasm problems, that's listed in the DSM, but
it has nothing to do with somebody being unstable.
Q. So the fact that gender identity disorder is listed in
the DSM, does that tell us anything one way or the
other about whether the condition has a
physiological or biological cause?
A. No, it doesn't. It's very controversial even within
the Benjamin Association to have it listed in the
DSM. There are many people who argue it should
be moved over to a medical kind of diagnosis as
opposed to a psychiatric diagnosis."

The "Benjamin Association" is now the World Professional Association for Transgender Health. Dr McHugh is not a member, and never has been. He's no more qualified to be than a podiatrist.

"Dr Cole was asked if he was familiar with the criteria for gender identity disorder in the DSM?
A. Yes, I am.
Q. And do those criteria refer exclusively to the
conflict between the person's gender identity and
their anatomy as well as distress that conflict
causes?
A. Yes.
Q. Is there anything in those criteria relating to having
any kind of bizarre or disordered thinking or
behavior or to any kind of emotional unbalance or
instability apart from the distress caused by having
the wrong body?
A. No.
Q. So would it be true that being diagnosed with GID
does not mean that the person is otherwise unstable
or disturbed or mentally ill?
A. Absolutely.
Q. In practice, are transsexual people who have
completed their gender transition anymore likely to
have psychological problems than non-transsexual
people?
A. No."

This is all on the public record, in such legal cases as Kantaras vs Kantaras. The Family Research Council is aware of this. However, it doesn't fit their religious viewpoint, so they omit it, instead adducing Dr McHugh and his...eccentric... ideas yet again.
