You're talking to a brick wall. His retort will likely be something along the lines of: "like I said, don't go to concerts then". The idea of including people that have some kind of hardship is totally foreign to so many people. Even when it's something simple that harms no one, takes nothing away from anybody, and they wouldn't even be aware of going on unless someone told them about it. Hopefully I'm wrong though! And I appreciate that someone still has the patience to shout into the void the obvious human compassion that should be the bare minimum standard though!
