If anything, the commenter's circumscribed scope of discussion only reinforces the point that they are informed by personal experience and not the internet echo chamber. Whereas you are throwing out these gatekeep-y acronyms to establish transit advocate street cred.

In my town the issues are rail trails and kids dying on e-bikes. Are my opinions on rail banking invalid if I don't know all the rules about wheelchair access ramps at the station? Come on now.

If you're going to post something as contrarian as they did then yes. Cars are popular and the American built environment is oriented around them. You might not like it, but nobody will take your seriously if you don't acknowledge the status quo.

The exact set of topics they brought up are very online. I may be wrong about their experience with urbanism but it literally looks like something out of r/fuckcars
