Or, the father truly thinks that this is a way to express his feelings about his son’s perceived homosexuality in a way that will promote society’s acceptance of homosexuality, in general, and in particular, acceptance of his son’s homosexuality.
Just another hypothesis.
Or as Wu suggests, the father is an ideologue using his son as a pawn to promote the issue of society’s acceptance of homosexuality.
Also a hypothesis. Not my first hypothesis, as it is also difficult for me to conceive of a parent that loves an ideological agenda more than his own son.
Or, as Lois implies another hypothesis, someone got a picture of some anonymous little kid, put the caption on it, and posted it on the internet, to promote their own agenda.
It’s a mystery. Will we ever truly know?
