I just think you can't judge everyone else's mental state and readiness to take charge by your own, and vilifying / shaming someone for being 40 stone isn't going to help. They have to be ready and able to make the change - I'd rather the facilities existed so they could have some dignity in their lives / treatment even though I'm not getting a direct benefit than they didn't, simple enough.
People say 'surely that should have been a turning point?' but that could be applied to many of us here at many times in our lives - maybe when I was 16 and a size 16 and got harrassed in the street it 'should have been' a turning point, but it wasn't, and there were many other occasions where it wasn't, one day for me it just clicked. The same goes for these people, saying you don't like the freak show aspect but then in a second breath demonising / shaming people above a certain weight is kinda hypocritical to me and I know that were I at that weight it wouldn't help.
I think people have reasons for not doing what we are doing, but we shouldn't hate them for it, or deny them the same level of care they've paid their taxes towards and deserve as a basic human right too - we should understand that they will come to it on their own terms as we did. IMO
