That clip is rather insensitive slim, especially to those who really are suffering with this debilitating DISEASE.......... and that's what it is, nothing more, nothing less.
Unless you have actually experienced it personally, please keep opinions to yourself.
The people you are calling losers are people who usually have an imbalance of chemicals in the brain, rather like when hormones go out of whack. They can't help it, it just happens, and to say something like that, I find very cruel, I would put that sort of thing down to "playground politics" type stuff.
Be aware, it could happen to you, at any time, and on any day. Would they still be losers then??
