My mother has it and researching it has become her hobby. She spends hours looking for looking it up on the internet, joining self help groups and the like."
Does it never occur to the likes of you and MegaBat that the reason somebody might be doing this is that they are in utter despair at having their health and whole life ruined by an illness that nobody has a cure, or even an effective treatment for?
How desperate do you think you would feel in that situation? Do you think you might take the initiative to Google the fuck out of the condition, in desperate hope that you might find something that might help, or even cure it?
Does it occur to you that people might want to join support groups to accept and offer support to those who really get it? As opposed to all the nasty people sneering at them? Do you realise that being chronically ill, trapped and thwarted is incredibly lonely? It can be soul-destroying.
MegaBat do you get the irony of people like you - who are not in any way affected by it - being annoyed at the sharing of memes and the like? Has it ever occurred to you that if you and your ilk were to open your minds, accept peoples' suffering and extend some compassion towards it, that they wouldn't feel such a strong need to bang the drum on raising awareness? You are part of the 'problem' (as you perceive it), here.
And just why does it annoy you so much that somebody wants to raise awareness of the illness that is disabling them, anyway?
