The relationship is repellant to the son. If it isn’t repellant to you, you are sick or evil. It’s that simple.
I AM repelled by the relationship. I have seen been in the home of two homosexual men who had adopted two boys, and one of the men was mentally, emotionally ill - hysteria, suicide attempts, a terrible environment for children - how did he and his partner ever adopt? Answer: lots and lots of money.
OTOH, I have known two lesbians who adopted and seemed to be doing a reasonably good job, other than not giving their children a mother and a father. My husband has cousins raised by his lesbian aunt and they turned out okay, better than his sister, for instance, who was raised by a mother and father.
In the California case we know none of the particulars except that the men were homosexual and the son stabbed them. He might have been mentally ill, or on drugs; he might have been abused; he might have wanted to make it look like an outsider did it and inherit, any combination of the above.
We don’t know. He was old enough to walk away and make his own life. He chose otherwise.
Any man who isn’t intrinsically nauseous at the sight of 2 men being physically kissing one another, is either gay themselves or been trained to not be.
Sorry folks, feel liberated all you want but no straight man can watch two guys kissing without the urge to vomit.
