It’s easy to search it yourself, but there are 10 states that haven’t expanded Medicaid. People in these states who are “just” poor (not disabled or children) do not have access to low/no cost healthcare as you suggested.
Reading someone saying they wish they could get their back fixed and complaining about rich people’s pets having a better standard of healthcare than people, then jumping straight to “they hate dogs and want them to die of cancer” is bad faith. Their feelings about dogs are clearly not the subject of their comment. It’s a complaint about the system that has left them without adequate access to healthcare.
