I hope this reply will help to change your way of thinking. Being disabled or handicapped is not usually a choice. People have fought to keep your country safe and have sustained injuries in doing so that cause them to be physically incapable of exercising, walking or standing for more than a couple of minutes. Do you think these people should be denied the ability to go on a vacation now? Why don't we deny blonde haired people. Or maybe let's ban Jewish people. Is a scooter really such a bothersome thing for you to look at?
