Irony, or chickens coming home to roost? It doesn't seem entirely unreasonable that a generation which has continually been told "freak you, we own this world, we'll do whatever the freak we want with it and there's nothing you can do about it" now doesn't really care when the narrative becomes "hey, please make all these sacrifices to your daily life because of this illness that is medically insignificant to you but could kill significant amounts of us". Obviously that's not a conscious train of thought for most, but the willingness to behave in the interest of a particular societal group being significantly reduced when that group has proven itself to be uninterested in doing their part is fairly logical.
It isn't irony, it's cause and effect.
Chickens coming home to roost? Hey you were an poopchute so I don't care if my behavior kills you.
If people can't tell right from wrong, they can never take the moral high ground again.
And the reality is the majority of all age groups are going to survive this. So if they think saying freak you I don't care if I kill you won't hurt their cause. Then maybe they deserve those jobs pushing shopping carts
Plus if they kill off all the old people then whose basements are they going to stay in?
