Exactly, there are a small portion of people who can't help it and are genuinely disabled. Which is why they have the relevant medical certificates for those conditions and can use special entry and so forth. Of course I'm not going to be having a go at someone who has no control over their unfortunate condition.
But as Alex B said, that is the minority. And it's exactly those that "can't walk" when it suits them that disgust me. And then you look at what they are turning their children into too, that's really sad.
Then you have the other group that have a minor condition and then use that as an excuse to give up and take the easy route. I'm sure a couple of you above would love to be able to run around and get the weight off if you could when others are like "oh well I won't try now cause I can take this easy option and society will pay for it."
America doesn't understand the word No, fortunately Australia isn't like that.
