Assuming you mean people who want to lockdown indefinitely / until a vaccine is found, it's a combination of those, and an inability to see the 'bigger picture'. There are loads of them on social media feeds; a selection can be found
here.
While I'm firmly opposed to the 'lockdown until a vaccine is available' brigade, I can understand the reasons for the current lockdown (with sensible easements) continuing until the end of May, but I think that enough is enough by that point. We could lockdown until a vaccine is available and we'd still have deaths from this disease but sooner or later we have to look at the bigger picture.
