Why would you say a mean thing like that! To you they are idiots but the simple fact is that they live in a different place and, in that place, Covid just isn't real. There are several reports, for instance, of people, in the hospital, dying and claiming that Covid isn't real whilst they do.
These people are not idiots, they are only mentally challenged. You should show them kindness and understanding and hope that the police put them away before they hurt themselves.
