I view it the same as other socially accepted delusions. We take them at their word. When a person with a penis and a y-chromosome identifies as a woman, society dictates that we use feminine pronouns and call her Caitlyn. Articles are published explaining that that the y-chromosome isn't determinant of sex.
When a woman claims Native American heritage with no evidence, we take her word for it. When another woman identifies as black despite her parents both being white, society creates a new term: trans-racial. Modern western culture dictates that we normalize to the outliers. Hey, at least their not shooting up churches and malls.
Plastic ficus tree enthusiasts! Why an artificial ficus? The real trees are so easy to grow. Damn them for trying to replace living plants, all for the ease of not watering! Stupid artificial subculture.
