A Straight Pride parade? Yes, it was a real thing. As much as it might feel good to some people to use such a thing to get their "digs" in against the LGBTQ, etc. lobby, it makes me wonder if that was the real motive behind this parade. Let me begin with an illustration taken from children's literature.
Our kids are avid readers. When they were smaller, they used to read a lot of old Frog And Toad stories. Sometimes we read them together. These characters are quite comical but there was always a moral to every story. These books made our kids giggle a lot, but they were always learning something from them despite not exactly knowing they were being taught.
In an article by Joshua Gibbs, a high school teacher in Virginia, he summarizes four Frog and Toad stories that he read to his students - "Cookies", "The Lost Button", "Tomorrow", and "A Swim". The students concluded that each of the stories taught virtue in opposition to vices. The vices are gluttony, anger, slothfulness, and pride respectively. Each story demonstrates the characters learning the competing virtues by hardships, self-denial, and self-control. Again, they're perhaps not overtly presented as character lessons, but they're in there.
Gibbs then demonstrates a contrast by reading his students a modern children's book called Madlenka about a young girl by the same name who has a loose tooth(I perused it on Scribd, but you can probably find it almost anywhere). Everyone celebrates her loose tooth despite her not pulling it. Somewhere in the story, the tooth falls out, but that part is conveniently skipped in the book. The students concluded that in the story "nothing happened". There was no drama, nothing was overcome, no lesson was learned. The key takeaway of the story was to celebrate... something or other.
This celebrate-everything idea has become a major part of modern parenting philosophy. Undoubtedly, many of the millennial generation (not all) presently trying to fundamentally change our culture were likely raised this way. Their vices (along with everything else) were probably celebrated to the sound of parents clapping their hands and proclaiming "Yay!!!!" for no good reason. Virtues were likely rarely mentioned because that might challenge the child's nature and make them unhappy. Now, these people are adults, at least by legal designations.
I obviously don't know the motives of the group Super Happy Fun America that apparently organized the Straight Pride Parade, but intentional or not, they may have provided our culture with a fitting object lesson- the celebrate everything culture pervading our society is childish, stupid, looks ridiculous, and makes everyone hate each other. I think the Straight Pride parade was just as dumb as Gay Pride parades that celebrate sin and debauchery. But perhaps demonstrating the inherent idiocy in celebrating everything was exactly the point.
