Schizotaxia and how madness is part of humanity

I'm reading
The Silent Side of the Spectrum: Schizotypy and the Schizotaxic Self
http://schizophreniabulletin.oxfordjournals.org/cgi/reprint/sbq008v1

and I came across this passage
"
''genetically determined integrative defect, predisposing to
schizophrenia''and the term schizotypy for a subtly
deviant psychobehavioral organization, reflective of
interactions of the schizotaxic vulnerability with environmental
factors.
"

Schizotaxia is a concept that's 30-40 years old. My understanding is
that it's a genetic vulnerability which, given the right circumstances,
can turn into a varied of disorders like schizophrenia or
non-pathological states of being like schizotypy.

Schizotaxia is one of the reasons I feel that one day people will argue
that schizophrenia is not a mental illness per se. It is a term that
describes the hypothetical idea of a gene that makes a person vulnerable
to a certain behaviour and the authors of the paper consider schizotaxia
pathological. It doesn't have to be that way. There's another paper in
the same issue of Schizophrenia Bulletin which I'm unable to access
however the topic is the relationship between schizotypy and creativity.
There's an often noted link between the two however I am unsure of the
evidence.

The idea of a genetic pre-state, to me, means that this is part of who
we are as human beings. Since the damn of homo sapiens there has been
this gene which predisposes people to the schizophrenia spectrum (from
schizotypy to schizophrenia).

My fear is that one day with genetic screening of embryos parents will
want to remove any chance of their child becoming a schizophrenic, just
as they will attempt to get rid of all hereditary physical diseases.
Perhaps it may even come in the form of a future government measure to
prevent mental illness by removing the schizotaxia gene from the gene
pool. After all, the consensus of mental health, science and mainstream
society is that schizophrenia is a terrible illness and anything at all
should be done to prevent schizophrenics from existing.

It's really, really, really bloody important to use the hated noun
somethings. "A person with schizophrenia" is not correct. Here's why.

In the 1970s pro-homosexuality campaigners used the genetics research to
show that homosexuals were a normal part of the human race. There may be
a similar sort of gene that can predispose a person to become a
homosexual. The logic applies to schizotaxia and whatever other genetic
predispositions for mental illness that will be discovered in the next
century.

The opportunty to understand an undividuals b behaviour and make up as
part of a genentic vulnerability is great in a theorectical abstract.
It's when people start to consider what to do with it that the problrms
will happen.

I fear that society doesn't want schizophrenics just as it doesn't
really want blind or physically disabled people. Not really.

Life is easier without socially ugly people. Parenting is considerably
easier if the child is....compliant and obedient. Life is easier if
adults are all the same and fit in. Those and other excuses could be
used in the future to remove the schizotaxic, just as osciety will
attempt to remove the blind and, had progress not happened in the 20th
century, society would attempt to remove the homosexuals through genetic
means as well (in my opinion).
