Spiritually, disabled people can usually go outside/build communism. "Go outside" is really about logging off from your internet patterns and trying to have human interactions, which you can do from home in case a disability makes literally going outside uncomfortable or impossible.

Of course, with generalizations we should also understand that there will be exceptions but that naming them right away would prevent the call to action from being pithy. So if a person's disability precludes building socialism, I'm sure OP and others would understand.

Though I would say that there are many ways to build socialism, so even someone that thinks they can't might just be unaware of ways they could help out.
