@SecondHandStoke “Queer” is fine as an umbrella term, but human beings love their categories and distinctions. Otherwise, we wouldn’t even need “queer.” We might not even need “human.” There is also a practical reason for the increased distinctions. When we only have umbrella terms, we tend to treat everyone under them the same. But imagine if we assumed that all human beings had exactly the same needs, desires, and preferences. We’d have an entire world based on the most comically tragic flaws of Soviet Russia: one size of shoe for everyone, bread and cheese for celiacs and the lactose intolerant (or perhaps no bread and cheese for anyone), only one kind of beer. Understanding and being comfortable with one’s sexual identity are too important to a life well lived to paint in broad strokes here.
And I’ll assume you already know that a lot of the entries on that page are there as a joke.
