You did this with teachers too--and I am a teacher. I bristle at the applying "hero" or "heroic" broadly. Some are, undeniably. Many are very good and do the job admirably. And many, frankly, are just not. Working in a caretaking profession requires a lot and some, possibly many, are just not cut out for it.
I'm tiring very quickly of the turn the healthcare profession has taken. From the dancing nurses days to now, whining incessantly about how full their wards are. Well, mostly, they're full because greedy hospital admins have been cutting beds for decades. Now these healthcare providers are hot on blaming people for their diseases, most especially "the unvaccinated". Right, that's a terrible move. If you did that as a healthcare provider you better only care for vegan marathon runners who don't drink, don't smoke and have never done drugs. Otherwise, keep your mouths shut and do your jobs.
