It sounds harsh but yeah, I agree with you. How many adults are in the picture? And none of them could pool their money together to help? Nobody had savings, retirement, something to pull out of?
As someone else already said the fact that he's still alive after a year is impressive. According to the American Cancer Society, the one year survival rate for pancreatic cancer is around 20% so he's not long for this world. Given his diagnosis, J's dad should qualify for Kancare, Kansas's state Medicaid program which would cover all of their medical bills, in addition to other federal benefits. In her post J mentioned that they fall into the "medicaid gap" meaning their income is too high to qualify--whether that's from social security alone or some other income I don't know, but his diagnosis should preclude that. It's possible that he applied and was denied, but that seems unlikely. Not that I would expect J to share such detailed information, the family shouldn't be expected to share that and internet observers are certainly not entitled to it, however she is begging for money ostensibly to help pay for his care.
What they really need is a social worker who can guide them through the available options and help determine his best course of action, rather than wasting money on treatments with dubious benefit. That is a shitty feature of our for-profit American healthcare system that patients are offered treatments basically ala carte often without clear clinical guidance, so J kinda almost has a point--but to be whining about capitalism when her family should have access to some of the only "socialist" benefits available in this country, social security and Medicaid, is the height of irony. It's not like people who suffer car accidents, or hell even less terminal forms of cancer, who recover and are expected to pay off their massive medical bills on their own.
That just speaks to the total lack of self-awareness which is par for the course with these blubber buckets. I daresay that her father's condition might inspire J to reflect on her own mortality, given that pancreatic cancer has a genetic component (in addition to other risk factors like obesity and diabeetus) and make some changes in her own life, but that would require introspection, accountability and discipline so that's obviously never going to happen. Just go right back to gorging and internet panhandling.
Edit: in that screenshot of the GoFundMe donations, a Whitney Thore donated 1k is that THE Whitney Thore of TLC infamy? lolz of course they would take the opportunity to namedrop while shamelessly begging
