As per the link you supplied: Conclusion As a result of everything I have read, learned and experienced as a mental health worker, I long ago concluded that homosexuality is not a matter of choice. Instead, it seems quite clear to me that there is a combination of genetic and biological factors that cause people to become gay. Choice and willfulness have nothing to do with who does and does not become homosexual. Those who are gay have no more choice over their sexual preferences than those who are heterosexual. Vegan clearly not the same as being gay
