I for one am quite interested in urbanism, am straight, and prefer to listen and learn, and if needed, ask questions or stick my foot in my mouth as I am quite human. By contrast I know someone who professes to be Bi but hates urbanism, and prefers to surround himself with 20-somes to feel superior and justify his "dark" past.
In my experience people fabricate or only promote narrow perceptions to prove their point for survival, for good or bad, that's the nature of propaganda and ignorance. And this is why I don't see the need for labels, they only lessen who we are as individuals and promote stereotypes.
