Born Gay? by Dr John Tay

I understand that this is a sensitive subject but I choose to post this as I believe in God’s created nature. I personally think that there are many gays out there who are talented and brilliant in what they do. Yet, their lifestyle choice is not beneficial for them in the long run as it runs against our created nature. Please note that I do not hate or discriminate, but from a position of concern just as a friend who will advise a friend if he/she is gorging himself/herself with food that will eventually cause life-threatening health problems.

BORN  GAY? Examining the Scientific Evidence for Homosexuality

By Dr John S H Tay (2010) ISBN 13:978-981-4270-17-5 ISBN 10:981-4270-17-2


 (Summary by Dr John Tay distributed with permission from the Publishers)

This book is a review of important scientific papers published over the last 20 years concerning the roles of genes and environment on homosexuality.  The book examines the statement “I am Born Gay”.  The resounding conclusion is that the role of genes is far less important than the role of the environmental factors.  No properly qualified geneticist today will ever say or agree with the statement, “I am born Gay, and I cannot change”.  Indeed, no form of human behaviour is ever solely inherited.  Genes produce proteins, and not behaviour.  Behaviour is much more complex than a single protein.

For a condition or trait to be inherited, without any influence of the environment, the “heritability” must be 100%, for instance, colour blindness.  The heritability of human intelligence is about 75% whereas the heritability of male homosexuality is only 26% (in the key paper based on the Australian Twin Registry, page xxviii in the book, this figure of 26% was not even statistically significant).  In other words, environmental factors account for 74% of male homosexuality. Environmental factors are clearly much more important than genetic factors.

The scientific community knows these facts for many years, but public opinion is moving in opposite direction, because of the lies perpetuated by the media and the gay activists.  When a lie is repeated often enough, many people will believe this lie. The book does not mention anything about God, the Bible or morality.  It focuses on the scientific papers and explains the basic concepts. The intention of the book is that key leaders in the nation, especially the politicians, members of the parliament, community leaders, principals, teachers and others, should know the truth and the facts.

A key thesis of the book is that if there is a massive disregard of truth in the society, that society will collapse.  Examples are given in chapter two.  Those who raise the question “What is truth?” are people who have rejected truth.  Truth is easily understood and is objective.  Clear examples are given in chapter two.
