.... trying to justify not having any children because he's a homosexual.
Wow, well I missed that. Thanks for pointing it out.
No.
Because he is Promiscuous.
Nearly all gays are promiscuous, but there are promiscuous heterosexuals and they spout this same crap since parental obligations impinge not only on their own free time for sexual adventure - but parental and/or marital obligations on the parts of others reduce the available partners for their never ending lasciviousness.
Most of them hate God for creating a world not conducive to an eternal orgy, and they definitely strive to destroy the institution of the family - in order that there might be more playmates for their immature lifestyle.
