I can kind of see their thought processes there. They're sharing right-wing media so they're likely already primed for those biases, plus that article title is intentionally misleading by suggesting asylum seekers will by default get priority over all other patients. It isn't until the sixth paragraph that they admit it's priority care for vulnerable people which is a group that happens to include asylum seekers and undocumented migrants (terms which this writer uses interchangeably, because of course they do). Very poor journalistic integrity even for a rag like this one, imo.

This type of article is intentionally misleading and written primarily to rile up people with poor media literacy. Making people angry makes it easier to manipulate them, and vulnerable groups are naturally less able to fight back so they're an easy target.

In an ideal world after being challenged they would have reevaluated the source and their beliefs. In practice very few people do that and they just get more entrenched instead. Especially if it's someone anonymous online just telling them they're wrong.
