I think we should follow the example and find ways to demonstrate support for heterosexuality.
Homosexuality is a psychological dead end, and like a recessive lethal gene in the gene pool, it keeps popping up until it finally mutates into something else, or the culture that forms it is exterminated by a clash with another culture that strongly despises that character trait, in a crude form of societal cancer treatment.
The Universe is a cruel and unforgiving place.
