Because, like others on here, I've known people who have learning disabilities, autism, or mental illness. I find posts belittling people in any of those situations, or unbelievably slagging off suicide victims because it made them late on a train journey, offensive.
I think you're right, many...
Yes I have. The odd NSC post belittling people who are variously suicidal, suffering from mental illness, or have a learning difficulty, are all very offensive. Being insensitive, selfish, ill-informed, low and dim.
