I liked this because it was a funny hot take. However, you're not correct about this being discrimination.
In emergency triage your age and health have a lot to do with whether you are expectant or saveable. When there is a mass casualty situation (such as a disaster, attack on an FOB or something, or a virus like this one, etc) people are classed into how resource intense maintaining their survival will be. In these situations, the elderly and chronically ill will be the last to get help because you can save more lives by taking the resources you'd use there and help people who aren't as sick. When it comes to distributing consumable or limited quantity medical equipment the people who are more likely to come out of it alive will be given priority. This necessarily excludes the frail.
It's an unfortunate consequence of overloaded hospitals and one of the reasons the casualty rate of a virus skyrockets under extreme hospital load. It is also the reason I really strongly dislike all of the conspiracy theory on this site about the virus. For every young person who goes out and exposes themselves to this an elderly or chronically ill person will likely die - either through infection or be denied a bed due to the ignorance of the very people the hospital will likely help in a mass casualty situation.
Do everyone a favor and stay inside. The more beds the hospitals have open, the more people can get treatment when they need it.
