It's a feature present in all anglosaxon jurisdiction: nothing can be discussed in terms other than their political implications. Discussing the validity of the herd immunity argument is equivalent to considering a sort of genocide, and cannot be an honest and sincere discussion of a scientific theory. Fortunately Swedish gov didn't see much merit in the argument, as there isn't.

It's good to know some jurisdictions haven't lost the ability to discuss things on scientific merits just yet.
