The son was nothing but a nutcase. Most gays are. This one just made things worse by being a druggie.
The son apparently was mentally ill and a drug addict. We don't know whether the father was or not.
To you all that matters is being able to attack him for being gay- and you had also hoped to attack the family for being Muslim.
That just didn't work out for you- when your fantasies and speculations collided with the facts.
